Create a ''ASK" Transmitter and Receiver by using some Chinese cheap encoder decoder ics.
Sorry to say
this kind of ready made solutions are not useful.
Hello, the electronoobs.com webpage doesn't work, i was working on creating the brushless motor arduino drone, but without the webpage i can't find the eschematics or the code, could you please fix it or upload it elsewhere, let me know please, thanks
Your timing is perfect. I was looking for a circuit to help me make a rotor controller for my indoor antenna.
I will set it to rotate in one of two directions (dependent upon which button I press) for a short burst of time. If I want it to move more I could simply hold the button or press it repeatably.
Since you have done all of the hard work for me this project will go much easier, Thanks for the great video (as always :) )
I wanted to make this project.. and to see that I have made something similar to yours makes me happy.. good work your projects are soo beautiful
I love this project. I got a pair of those 433MHz RF modules for my channel but i never got around to using them. I think this video paints a good picture of the possibilities. Well done Electronoobs
Not yet watched entire video, will watch tomorrow, it is late night, but I will now be able to control a solid state relay, I ALWAYS had trouble controlling it.....IT JUST WON'T TURN OFF!!!!!!!!!!!!!!!
Awesome as always.
I honestly believe that this video deserves more views.. great work and explanation
That is a very cool and useful idea
Hell no!! Never trust a metal piece sticking out of a power plug like this antenna!!
I think you have experience that🤭🤣🤣
@@motilalsuthar4048 Oh yes, when I was a kid I pulled out a defective plug. Never will forget it!
Sun day is day of Electronoob
HAHAHA That's right!
science is the engine of prosperity of life, thank you Electronoobs🙏🙏🙏
:)))
Thanks🙏
Excellent video
The way the antenna vibrates makes me happy 8:08
Great work there , a question though : how hard is it to encrypt the signal , I mean if I need to control a door someone can pickup the code and hack me , I want something similar to car remote locking/unlocking, thanks !
maybe you should multiply the sent number by a unique KEY and have that same KEY on the receiver as well and by taht you can get the original number....
@@ELECTRONOOBS the problem with that method is that the key is always the same so someone can record the sent data and replay it to open the door , I think the encryption must contain the current time as a seed , I should probably imitate the algorithm used for cars
@@ELECTRONOOBS here's a video démonstration of the problem ua-cam.com/video/CA3XnGyD-SQ/v-deo.html
@@piiumlkj6497 Have one code to request a new challenge message, at which point the receiver will generate a random challenge and send it back to the transmitter. The transmitter sends the command along with a hash of the command, challenge, and a secret key. The receiver can then check if the received hash matches the expected value. Done right, it is very difficult to break.
@@NiHaoMike64 thanks for the help , your solution is elegant but it requires 2 way communication to be implemented which can increase the error rate of the device , I think rolling codes used in cars is a simpler approach , although I still don't quite understand how they can maintain the synchronization between the key and the car , what if for example I pressed the unlock key while away from the car ? It will go out of sync , I'll appreciate a suggestion on how to solve that problem , thanks again!
I like radio frequency circuits like high voltage high frequency low current circuits :P
Wonderfull project
You are doing a great job man
And if you'll want to have multiple receivers around in different places each operating separately you can write a single code for all of them.
Each receiver should be triggered upon receiving certain code, like numbers from 2 - 13 . The trigger-code will be defined by shorting digital pins with ground and corresponding arduino code should detect the shorted digital pin and start processing only appropriate commands. This way you can produce quite a lot of receivers with uniform hardware and firmware.
Super useful project. Inspires many possible applications. 👍🙏
Why didn't you use the standard PT2272 as you can use no power until you press the button that way it will last for years?
The SSR is much smaller but I think the current capability is also much less. 2A vs 10A!
Thanks. Good u explained just enough to understand each bit. just wonder what u would bring next-. Waiting......
How about security? Just in case we want to make many of this. To avoid interference with each other
Cool video. I Guess you can lower the consumption even more with attiny85.
love you sir you are awesome
This project is really good but the problem is that the transmitter is just too big. The physical size of the transmitter should be reduced the same way you reduced the size of the receiver. Also, making use of a more cubical battery can help with the small size of the transmitter. I built a similar project around 3 years back and used an ir sensor with an ir remote to turn on and off certain relays. I also ensured a good use of the old remotes that you all might have laying around in your house. It is also cheaper and more compact. Anyways, thank you for uploading this video as this is a perfect tutorial for make a low power arduino project that doesn't sucks all the juice out of the battery.
Please do a video on how to communicate i2c modules without wire and module library
Thx! Have you measured power consumption for 433Mhz and LoRa modules by yourself? 20uA looks too low for 433, these modules should consume more than 5-10mA, also LoRa module with 35uA is also very impressive.
Your videos are very cool
It's posible implement low power library en the reciver? If I want use it with battery too.
very nice project
Would still like to see how you can make your own RF module with separate components.
Hi. Can work all button same time? Can you tell me name of second transmitter ? 500m
hello friend, I am your follower, I like the project you created, can I know the type of software you use to draw the schematic above?
I am thinking to do this with a esp8266 transmitter and receiver and thinking to add a 433MHz radio to it and to make the receiver work on as a web server.
Cool
Amazing man... Do a 3 arduino Nano bus project
Amazing work
Hy friend congratulation how to control motor servo with 433mhz module and arduino thanks
Hey dude listen i wanted to make a rc f-22 raptor and im a little confused at the hc-12 -- Arduino coding and can u help me out someway? Please help im a robotic hobbyist frm india
All I have is this: electronoobs.com/eng_arduino_tut96.php
Interesting, but I can grab a zigbee power switch from IKEA with remote control button for $20. And it is certified for safe use - no problem to touch antenna sticking from the power socket :)
awesome stuff but mine dosent work :(
After extensive debugging, its the sleep mode that doesn't allow for transmitting even though the code is the exact same.
Hi! I am working on your brushed drone project but I am unsure of one thing. The 16Mhz model of the Arduino pro mini has 5V and the battery I am using is 3.7v it will still work, right? Also, will it work if I use an Arduino nano? I am new to engineering these things so any help will be valued thx!
Hi how far can you control the socket? can you communicate by 5 meter far?
Why you didn't use 5v for the receiver along with a 5v relay ? What's the reason for using 12v only.?
Nice video.
Well, you could just upload code without bootloader and connect the push buttons in series to the power of arduino and it consumes 0 amps when not in use. This is also a great soultion but i tried that way and it also worked.
Even when i know very well the metal sticking out is the antenna, I cant trust it with the word AC in the sentence. hahaha😆
8:10 antenna shaking
Sir, it is great project. I upload the transmitter code but it consume about 7ma current. I want to reduce about less than 1ma. Please help me sir
Hey electrogenius please tell me if we can drive 2-3 amps through the irFz44n using 5v of arduino nano if yes then why my arduino died 😔😥
Why can't you file a patent on this project. What is the criteria for patent filing.
How does your receiver not generate garbage data? Does that model not have AGC?
I made a wireless controller long ago and I used basic error checking and crap still got through sometimes.
I may need to pay more attention to pull-up/down resistors
Amazing how you reduced power consumption of Arduino
Great project, but for safety reasons just use a standard rf plug and decode it for use with arduino!
Hi as always nice video..
Why don't you use Attiny instead of Pro Mini to save space?
You can reduce power consumption more that by turn off the ADC which has very power consumption
Yes, I've done that, thanks!
Keep it up
Hey, what about getting into PIC now?
Which are the other modules you showed? Thanks?
Can attiny works on this project? Probably it needs less energy.
Foarte tare am construit și eu asemena circuite
:)
Are the four buttons working?
Bro ur the god
Nice bro
Very smart
what if one would like to reduce the power consumption of the receiver? I' ve tried to turn on and off the receiver but its wake-up time is just too slow (150 ms). Maybe the problem is about the Arduino libraries that are slow to send messages... If anyone has managed to solve this problem and created a long-life battery receiver, just let me know ;)
Can I steal this ..?
Can you make your own mini travelling hotspot get free net or hotspot for free with any charges
Why do you need an Arduino ? ? ? You did not explain. You could do without it I guess. (a 555 could do it as well).
Bravo :)
Can you pls do a video only for arduino sleep mode?
Nice
how to make bluetooth controled drone
Hello Electronoobs. I'm 29 years old. is it too late to start learning electrical engeneering?
Its never to late!
Be careful ! If galvanic isolation is broken the external antenna can become live (and obviously lethal!).
True. Maybe putting that o. The outside was a mistake after all... Thanks!
What is the use of four button??
Add multiple relays and control them with pins D2, D3, D4 and D5
@@ELECTRONOOBS oh thanks for this great project.
I will try
Ai putea sa îți faci un server de discord ar fi mul mai ușor sa comunici cu restul lumi și nu ai mai primi atâtea mesage.
Make a RF based wireless water level controller which operates automatically when the water level decreases and shutdown the pump when water level reaches the top
Why don't you use a capacitor dropper circuit to power the receiver, that way it is even more dangerous ;-)
Can someone tell me if the internal clock (for millis) is deactivated when sleep mode is anabled ?
Not sure, I'll have to test that...
@@ELECTRONOOBS thanks you are awesome by the way :) I am 15 years old and I have learned countless thinks from your videos and even made my own drone thanks again and good luck with all your projects
Why there is banana in back ground😂😂😂😂
It's in every video
For scale.
It is better to use ATtiny
More smaller I think it is less power consumption

Is using 433 MHz legal in Europe or America? I thought that was an Asian frequency?
Legal in Europe.
@@divingquokka Seems legal in Europe but limited to 10 mW in some countries and subject to interference from amateur radio. Not legal in the US where this frequency band is allocated exclusively to amateur radio. en.wikipedia.org/wiki/LPD433
Why is there a banana on the table?
Why is there a banana always on the table..?
banana for scale 🍌 - google it

its learning channel you can use this solution to trigger automation and other staff
@@ahmedelwan9129 as Electronoobs have lots of knowledge.
So he must create the stuff from the ground level
@@ahmedelwan9129 such kind of RF remote control switch is cost very less then he created.
Cool
