DIY Perks Hey. Make it battery powered using pulsed relays. Also try to make a two channel one for clapping two times for channel one and three times for channel two. Using (expensive) beefy relais may allow you to put on power strips for multiple appliances!
***** ... Batterypowerd? a batterpowered mains switch, so you can turn of your charger that charges the batteries for your clap-switch? now i see why you need two channels...
dicky dicky Totally wrong! The conversion of 250 Volts into 5 Volts using even a switching PSU is much more inefficient as just taking two 9V batteries and use pulse relays. So the circuit does only draw very low power to power the micro and only when a switching impulse is sent the relay is used. The batteries would last for at least one year and batteries are pretty cheap in germany. I could also use 6 AAA eneloops and recharge them EXTERNALLY. It's much better than permanently have a PSU on the mains... I just do not like it to do so! We pay 30 Euro-Cents each fucking KWh in fucking Germany! Congrats for almost free electricity in USA...
It is because of stuff like this why I'm starting to teach myself about coding and programming and also learning about all the different hardware and what it does. I ordered a raspberry pi to learn coding on and eventually I can add components to the pi so I can learn more about the hardware side of things. I'm sure it will take me quite awhile to learn all of this but my goal is to be able to create things like this guy. It's amazing!
This really does work nicely, congratulations for another excellent instructional video. I would like to add a very quick note about the circuit diagram. I made the mistake of wiring the output of the ATtiny85 as per the diagram which shows pin 2 and not pin 7. Only after this did I look at the datasheet pinout, and see D2 is pin 7. This is here to assist others who made the same error as me but look here for an answer. Love your videos😊
Wieder ein super Video! Macht wirklich Spaß deine vids zu schauen und ich habe echt Lust deine Projekte selbst auszuprobieren. Was ich besonders Klasse finde: Du erklärst nicht nur wie man es baut, sondern gibst dazu noch elektrotechnisches Wissen an uns weiter! Mach weiter so!
Made it myself!!! I found on tindie (searc: All ATtiny Arduino programmer shield) - which simplify the tiny programming the bonus is that it can easily hook the tiny micros....
Hey just a quick side note, I noticed that that relay was rated 125 volts. However it's always a good idea to use a relay rated twice the voltage you put through it. For example if you use 120 volts then use a 240 volt rated relay, if you use 240 volts then use a 480 volt relay. It will greatly reduce the risk of arcing and will be a lot safer.
!!Excellente GScott made a low noise amplifier, as always make clean projects with pros n cons well explained in short time, pretty like Andreas Spies...
Just discovered your channel. even u hardly am ever able to make these kind of stuff I've always loved these kind of electronic project channels keep it up
Just discovered your channel. even u hardly am ever able to make these kind of stuff I've always loved these kind of electronic project channels keep it up
I remember I built a clap switch with "one clap on, two clap off" feature 7 years ago. I used the output of my mic preamplifier (a simple transistor stage) and fed it to a monostable stage wired around IC555. the output clocked a decade counter (CD4017) and the second bit triggered a JK flip-flop for latching the output. It's amazing how a tiny MCU can reduce the part count so much! :)
Great job mate. I suppose you can add 3 and 4 claps switches depending on the timing and the number of claps right? Now THAT would be even more catchy!
Nic Brain if you can achieve the first step, which is the 1 clap then you can do the resrt.You just need an oscilloscope for that, something that i dont have. But the idea is measure the timing with the oscilloscope and put according delays on the arduino code.
Theo papa thanks for the fast reply . Because am a beginner On this arduino coding and stuffs iT makes things kinda harder . I dont know maybe u can help me make this code ? My aim is to turn different appliances On with different number of claps. For example 2 clap to turn a pc On and 3 clap to turn the tv On
i am afraid you should relax and start as everyone does. From simple stuff. Start by learning the basic commands and achieve manipulation of leds, stepper motors and then lcd screens. You ll gain experience this way. Controling high power devices like the ones you want require solid understanding of coding and most importantly of risks of electricity. So you d better take it slow.
i love your accent cus. everytime i use heatshrink i think "termal tshrinking ishulatoooooor". i love your work, you help me understand shit other people make really complicated.
I dont know why am i watching your videos, i dont understand electricity, im stupid at programming, i have no idea what are you doing, but i just love your videos, your inventions and voice :D have a nice day mate :D
I am a electronic engineering student from india great sir keep it up I learned so many things from you Please keep uploading new project Kindly can show with arduino uno ??
fantastic video man. I just gotta build this next! I have a room and the light switch is on the far wall away from the door. I always curse bumping into things to get to the switch. I bring a torch but this is sooo much better
Hi Greatscott, nice video! I was wondering what components would have to be replaced for the project to switch on/off AC appliances which require high power around 1000W?
Questions: 1/ have you tried this without mounting the microphone on the outside. i.e. in the box. Obviously this is not ideal, but how well does it work? I want to mount mine inside a wall backplate with a panel on top! 2/ Why do you use the ATtiny85 when you could use analog input of Arduino?
Hi GreatScrott!, nice project.... I was wondering, couldn't you use the mic voltage burst to activate an interruption, and thus keeping the IC sleeping until awaken by the interruption from the first clap ?
It would help if you were consistent with the resistor values you used for the project. The first circuit you showed at 1:40 sets a quiescent bias point around 1/3 of the supply rail (i.e. 1.67V) not the 2.5V you show on the 'scope. I appreciate that you actually want to bias the quiescent point closer to the negative rail to maximise the swing since the opamp can't swing to the positive rail, but you need to explain that, not leave folks with the false impression that a 20K : 10K resistor divider will give 2.5V. It won't.
I have a question. I have two fans in my living room and I was wondering if I could somehow wire this to the wiring in the wall instead of using a pole switch. Also maybe have two different types of clap so I can turn the fan and the light on separately
Hello I plan to integrate the following circuit in the lighting of a room, doing so turn the light on with clapping, how can I do to make her turn with Arduino is that with the switch already present? To turn this light in your opinion to the potentiometer value should be? I already tried the circuit on breadboard with a relay module and it works. Since the protoboard I used not find it anywhere you send me a link to buy it? Thank you for an answer, keep it up you are very good I follow you from italy.
Hey Scott, I have the electret microphone breakout board, lots of relay modules, an Arduino uno, resistors etc. Could I make this with an Uno, Electret board and relay?
I tied to see the peak voltage that I can get from oscilloscope but it wasn't showing any useful reading on it. Do I need to use the oscilloscope in some different mode. please answer it.
This is really cool, and actually quite close to something I was trying to do not long ago. I wanted to fit a lock to my front door and drill a small hole for a LDR, and use a momentary flashlight as a "clap". If you flash a specific sequence, the door unlocks. I never got around to doing it because for some reason, my code doesn't like putting out more than a volt on the digital pins -__-
First of all to mention that I personally use Atmel studio. Now I can not see anywhere pinMode(). This function configures your pin direction if it is an input or output. Take a look at this link fix that and you are starting from something. www.arduino.cc/en/Reference/PinMode
Mario G. Oh my god... How could I forget that?! **Ultimate facepalm**. I don't like using goto, but It's the easiest way I can loop something, it's the one I understand the most. I hate using "while" and "for" loops, they confuse the hell out of me. Thank you for pointing out my obvious mistake though.
Simple question but... what program do you use for drawing schematics? (like the schematic at 3:30) I remember that you said LTSpice somewhere, but it doesn't look like that and that's a circuit simulation program.
As always a neat project. I was however a bit surprised to see you still using your dremel and veroboard when you have a shapeoko? Looking forward to projects that include cnc stuff for that professional finish from this channel. Keep up the good work.
Hello great Scott I have several problems i --- I am using lm358 instead of ne5534 with the same connection. ii ----- at first the circuit was not working but then it reacts strangely. The led turn on for a very short time when I clap. iii ------ the led also turn on when I blow air to the mic and turn off when I stop
Great Tutorial! I am currently making this project. I am having a problem with my Arduino 1.0.5 software recognizing the ATTiny85 as one of the boards. Is there any other link I can go to for help on this? I have a mac by they way. Cheers and happy coding.
Can I use NE5534P instead of NE5534N? And can I use another 5V relay? The ones you used are quite hard to get in my country. Thank you so much for the videos!
Thank you, I tried doing my own sound activated project (Didn't care too much about double clap), but the problem I had was the microphone being very insensitive. Some times I could get it to register with what I considered a tiny noise some times I would do a loud noise and it would barely register. I am hoping using the amp that you suggested will help.
@Greatscott other various sounds does not trigger the attiny? I mean because many sounds especially form TV or Radio are likely the same as the rwo claps
do you have any suggestions for relays that can switch more power? Also it seems the relays rated voltage is 120V, with a max switching voltage of 220V. I wonder if it will be a problem
is it really safe to use switching of this moc3021+bt series triac instead of traditional relay , as we know relay provides around 10^6 click life and I have seen some relay contacts get sticked due to unknown reasons and we need to replace those and if they used in home automation it's really seems disaster so is it good idea to use triac as switch?
Could you have done it using a DFT? You could have searched for a signal with a certain fundamental frequency. I just bought my pic16f877a to put it on practice in this summer break.
Is it possible to use two switches in an Arduino and code : if one switch is high it will turn on pin 7 and if another switch is high it will turn on another pin.I tried it didn't work.is my code correct?: In this code state of push button on is buttonstate and 2 switch state Void loop () { If analogRead(buttonstate == HIGH){ digitalWrite(7, HIGH); else { digitalWrite (7, LOW); And switch state also like this.
Hello Sir, I'm from the Philippines. I would like to ask about the squares with red dots in the diagram. Thank you in advance for your wonderful response.
Great video again! Thanks for leaving in your mistake with the AC adaptor rather than starting again and cutting it out of the video. We all make mistakes :)
How do you remove the traces on the break out board so you can use an IC? I've used copper dot proto-board, but using a ton of wire is annoying. Thanks!
halo please i wanna make this too but what i wanna do is that for example when i clap my hands 3 times the light turns on , and when i clap 2 times another device turns on. please is it possible and can u help me with that ?
I'm very interested in this project but i have some issue in finding a site where i can buy all the components. Someone know a site that sell everything in Europe or better Italy?
greatscott if i dont have the AtTiny85 and i want to use the arduino what pins can i use for the outputs and inputs ? and what i have to change from the code??
I simply have no words for you. You're trully Great. Have you finished electronics in uni or..? That's not only creative and thoughtful, but also very smart. :) Nice job! :)
I replicated the OPAMP circuit and I saw that it's giving a 5v output even when there is no input signal. and when I turned on the signal there is no change in the output voltage. PS I only have a multimeter not an cro so I can't check the waveforms. could somebody point out why this is happening?.
Can any direct me to a video that can explain the 10 Bits of the AtTiny he talked about? I'm a beginning and as cool as this project is, I have no idea what calculations he did.....
Great project! Will definitely have to try this out sometime.
OMG, I NEVER NEW YOU WATCHED GREAT SCOTT, IM A HUGE FAN OF YOU AND GREAT SCOTT, sorry for capitals

This is the best frickin channel ever
fantastic video man. I just gotta build this next! I have a room and the light switch is on the far wall away from the door. I always curse bumping into things to get to the switch. I bring a torch but this is sooo much better
ThankYou , you were my inspiration for my new channel!!! Love Your Videos !
Always a pleasure watching your posts. Well done
GreatScott! You really need to expand this, add more output and clap patterns.
when you really use your creativity you can alot of things. and one those could be like this one. Nice One Man!
You deserve more subscribers dude. Awesome videos
+EveryLittlePixel Thanks mate ;-)
Hi Greatscott, nice video! I was wondering what components would have to be replaced for the project to switch on/off AC appliances which require high power around 1000W?
For 240v use relay for minimum 5A
I already feel for you when you will catch cold and keep coughing :D
Hahahaha lol
Great project.
Is it possible to control two or more sockets?. so, every socket has different number of claps or what is your idea... thank you
Questions:
1/ have you tried this without mounting the microphone on the outside. i.e. in the box. Obviously this is not ideal, but how well does it work? I want to mount mine inside a wall backplate with a panel on top!
2/ Why do you use the ATtiny85 when you could use analog input of Arduino?
1. No, I did not try that. 2. The ATtiny is cheaper and there is more than one way to skin a cat.
I've never tried to skin a cat, but I'll certainly head back to your channel for instructions should I ever need to know the best way :)
From the socket you used, I assume you use 220V AC in your country but the relay you used was a 120v one
Hi GreatScrott!, nice project.... I was wondering, couldn't you use the mic voltage burst to activate an interruption, and thus keeping the IC sleeping until awaken by the interruption from the first clap ?

Thank you for an answer, keep it up you are very good I follow you from italy.
It can be a bit annoying if you are watching a tv series and they start clapping? Then everything goes on and off?
Another great tutorial. I almost always learn something new in addition to what the tutorial is about. Thanks GS.
Cool project! Must try this
Wow.... man you are very very very dedicated.

www.arduino.cc/en/Reference/PinMode
And my friend please do not use goto. just never when programming on C/C++. Always you will find a way to do it with loops.

love all ur videos, never stop
Simple question but... what program do you use for drawing schematics? (like the schematic at 3:30) I remember that you said LTSpice somewhere, but it doesn't look like that and that's a circuit simulation program.
i think it might be eagle
As always a neat project. I was however a bit surprised to see you still using your dremel and veroboard when you have a shapeoko? Looking forward to projects that include cnc stuff for that professional finish from this channel. Keep up the good work.
Hello great Scott I have several problems
i --- I am using lm358 instead of ne5534 with the same connection.
ii ----- at first the circuit was not working but then it reacts strangely. The led turn on for a very short time when I clap.
iii ------ the led also turn on when I blow air to the mic and turn off when I stop
i don't have access to Most of your machines, Where can i buy a complete build one?
I have a sound sensor in an arduino kit but it already comes with a pcb with a potentiometer, do I still need to make an amplifier for it?
Great Tutorial! I am currently making this project. I am having a problem with my Arduino 1.0.5 software recognizing the ATTiny85 as one of the boards. Is there any other link I can go to for help on this? I have a mac by they way. Cheers and happy coding.
What was the code for the clapping? Does it only work with claps as it's supposed to? Or any loud noise make it switch?
Where did you get the pcb with the lines of copper, I have never seen it before. Good video!
Can I use NE5534P instead of NE5534N? And can I use another 5V relay? The ones you used are quite hard to get in my country. Thank you so much for the videos!

is it really safe to use switching of this moc3021+bt series triac instead of traditional relay , as we know relay provides around 10^6 click life and I have seen some relay contacts get sticked due to unknown reasons and we need to replace those and if they used in home automation it's really seems disaster so is it good idea to use triac as switch?
great scoot you should connect a fan when your chilling and when you want it on just clap that would be great
turning my pc on with 2 claps and open programs with cortana. love it
Wow i am really impressed with this project...u did a good job man, keep up the good work! 😉
Could you have done it using a DFT? You could have searched for a signal with a certain fundamental frequency. I just bought my pic16f877a to put it on practice in this summer break.
Your channel name literally is my reaction
Sorry can you explain what is the capacitor for and what is the dc offset and increase of peak voltage for. Curious to learn . Thank you !!
If you have more than one, how far apart do they have to be to avoid false triggers? Is there some way to have them close?
Why did he add the transistor though? The relay with the flyback diode could've been enough to act as a switch no?
Very cool project Scott
Is it possible to use two switches in an Arduino and code : if one switch is high it will turn on pin 7 and if another switch is high it will turn on another pin.I tried it didn't work.is my code correct?:
In this code state of push button on is buttonstate and 2 switch state
Void loop () {
If analogRead(buttonstate == HIGH){
digitalWrite(7, HIGH);
else {
digitalWrite (7, LOW);
And switch state also like this.
Sorry for asking, but what software do you use for designing your prototypes? (I saw that you printed your circuit)
Can u make a video about relais? I'm so confused about their connection
Hello Sir,
I'm from the Philippines.
I would like to ask about the squares with red dots in the diagram.
Thank you in advance for your wonderful response.
Great video again! Thanks for leaving in your mistake with the AC adaptor rather than starting again and cutting it out of the video. We all make mistakes :)
How do you remove the traces on the break out board so you can use an IC? I've used copper dot proto-board, but using a ton of wire is annoying. Thanks!
Does the circuit change if I want to use a 110V American socket and not the 220V European socket? Please help!!!
Wouldn't this also go off with for example, someone yelling twice at a similar pitch and frequency?
profe una duda cuanto se de demora el bonbillo prendido o se apaga cuando quiera uno apagarlo aplaudiendo dime porfa alludame quiero aprender
What tool did you use to make the outline of your final circuit connections? And is integrated with eagle?
halo please i wanna make this too but what i wanna do is that for
example when i clap my hands 3 times the light turns on , and when i
clap 2 times another device turns on. please is it possible and can u
help me with that ?
Clap On, Clap Off, clap on clap off, the clapper! I had one of these in the 80's
I'm very interested in this project but i have some issue in finding a site where i can buy all the components. Someone know a site that sell everything in Europe or better Italy?
Can i make this for multiple outputs as 2o/p sockets or a socket and a usb charging port?
greatscott if i dont have the AtTiny85 and i want to use the arduino what pins can i use for the outputs and inputs ? and what i have to change from the code??
I simply have no words for you. You're trully Great. Have you finished electronics in uni or..? That's not only creative and thoughtful, but also very smart. :) Nice job! :)
Hello sir i was just curious, instead of arduino could we use a monostable circuit (my teacher told me) . Great video btw sir :)
Happy 100.035 subscribers!
I replicated the OPAMP circuit and I saw that it's giving a 5v output even when there is no input signal. and when I turned on the signal there is no change in the output voltage. PS I only have a multimeter not an cro so I can't check the waveforms. could somebody point out why this is happening?.
Can any direct me to a video that can explain the 10 Bits of the AtTiny he talked about? I'm a beginning and as cool as this project is, I have no idea what calculations he did.....
@greatscott if i dont have the AtTiny85 and i want to use the arduino what pins can i use for the outputs and inputs ?
wouldn't you be able to use a capacitive dropper to eliminate the need for a "Big" Psu?
can we use this circuit in addition of the switches that are already in the house to turn all the lights (10 amps switch)
wow, great scott really is great😉
"It is possible to touch 240 volts directly, if you are stupid, so, don't be stupid" - LOL--classic!
What if you are using 120V AC, how many amps would stripboard / solder support?
You could save space by replacing the Output with a short extenstion cord ( the end) :)
And what about a switch in the wall? I mean the one you use to turn on the light in your room.
