Schematics are great. They are a universal standardized way to give a graphical representation of a circuit. But they can be difficult to translate to putting components down on a breadboard.
In this video we look at a simple 555 astable circuit. The schematic shows the connections, but doesn't really tell you how to lay it out. We set up this circuit in the simplest way possible, using only 1 capacitor, one potentiometer, and a few jumper wires. - Наука та технологія
LOL, You just made the 555 a pile more friendly to me .. Thank You.
Welcome!
Am sure the 555 was out in early 70s...
I guess it's quite randomly asking but do anybody know a good website to stream new tv shows online ?

I watched this a few weeks back. Today, I did my first breadboarding since then. I applied these principles and it went so much easier than some of my previous attempts. Thanks for the teaching the things that others assume to be known.
The best 555 explanation ever.
Watched 2 or 3 videos before and didn't underatand a single crap about the IC. But this one video here, really hit the nail. You did a great job at explaining how to wire it, thanks a lot man.
Thanks
There should be a 555 fan club. Everyone loves it.
I agree
we need group chat that's the best way to learn more things share knowledge thanks❤
Umm, there is a club... Not only that, but there is also a career ...
Now seriously, I think I had my share of teachers throughout my rather short life. 33yrs, pilot. But you Sir, your calm, your voice, the sense of such a nice person that I got from you, the knowledge you share... I could just seat on a table right next to you for an entire day!!! Only with a notebook taking notes. Just something about you. Thank you!!!
Thanks Paul really enjoying your videos. They make electronics much clearer than 28 years ago when I was an engineering student.
‘Keep it Simple Stupid’ has to be one of the most brilliant pieces of advice that every educator, professional engineer, technologist, designer, and hobbyist should always follow in all of their endeavours. A genius makes simple work out of complex problems, and idiot tries to make everything as complex as possible in order to try to look as smart as possible.
I love the videos please keep them coming. I have more electronic components in my garage than the law should allow. Somethings are hard to understand but you just simplified my life thank you, you are a good teacher.
That circuit is a bloody ripper, so neat and simple, big help for beginners. Good job on practical demo,, thank you Paul. Great video.
Thank you very much for your video. I do need the KISS method, and have to learn 555 today. After viewing your presentation I will assemble an air pump. Thank you again. Stay safe and be well.
Very nicely done! I'm sure the other way with extra components exists for a reason, but this will help people get into timer circuits more easily when they are just starting out.
This is the best channel for learning electronics, Paul is such a cool guy
Great job!
I like it: a just barely good enough circuit. I'm working with these pesky little 555's in my Electronics 101 course, and practical tips are priceless.
What I did on my bboard is to wire both rails with Vcc.
In your example, I would've then, instead of routing a 2cm wire OVER the chip between pins 4 and 8, instead use a tiny jumper from the hot rail to pin 4.
Thank you so much for this video! I've been trying to figure out how to build something like this for a while and I had no idea it could be so simple and inexpensive!
I love your videos man. I was having so much trouble actually getting output from the 555 before this.
Absolutely brilliant, simple and practical explanation mate. Thanks heaps!
I enjoyed it and learned something USEFUL!! Minimal bits to do the job. Gratitude!
Great video, you just made it easy and fun to set up my very first 555 timer. THANKS A TON!!!!
Great tutorial and ingenious breadboard layout
Thank you for a brilliant channel, both old and new videos are just great. The '7Ps' and the "keep it simple stupid" were just fantastic. Thanks again.
Very welcome
hi Paul, i`m Steve and a total newbie to electronics, i know about some of the components, love watching your vids, funny in a good way sometimes but very very helpful, well done please keep going, thank you..
Thanks - that is what I needed- just a simple explanation, not some MIT bint going off on comparators and shite that go beyond me!
Love these simple circuits. Great for learners like me
Great video. My oscilloscope should be delivered today. Thanks for sharing. Everything about electronics is so fascinating to learn. Thank you much for sharing your knowledge. Artie 😊😊😊
Very cool video with the 555 basics!
"This is good, it's academic, it's to much". Got me tuned in ❤
Perfect...exactly what i was looking for. Thanks for sharing!
Excellent 555 lesson. Thank you for sharing.
Tried various circuits. This was the first one to work!
I have a favorite 50% duty cycle 555 circuit with just two parts parts! It will ALWAYS oscillate at 50% D.C. and it has 100% INDEPENDENTLY adjustable frequency and amplitude.
From the standard monostable, pull out the resistor at pin 7 and the cap at pin 5 and toss 'em! Now connect pins 2 and 6 to output pin 3!
* ONE POT
* ONE CAP
Adjust the frequency with the pot and the amplitude with Vcc
BTW: the formula for the frequency is given as: 1/1.39RC
ps
The 1.39 comes from 2Ln(2)
THANKS FOR THE GREAT VIDEO!!!
Sorry, I meant "ASTABLE"
Very straight forward - thanks
SORRY I AM FRENCH. SO MY ENGLISH...... POOR. IT IS THE BEST DEMO I NEVER SEEN ABOUT 555. THANK YOU.
So simple I got it to work on the first try thax man!
I love this guy! Amazing video
It's amazing how after 40+ years the 555 is STILL such a versatile IC
It's over 50 years now as of 2021
@@SoulStealy yeah I wasn't sure off the top of my head exactly how long, but I knew it was at least older than me 😂
Electronic components, not to mention the theory and formulas centuries old have hold up remarkably well.
The first chip I ever used while I was still an apprentice (late 70's)! Like me still going strong(ish)!
+gartmorn nice!
Nice video! Thanks for teaching
Very nice detail video. Thanks for sharing.
This video has 555 likes, it should have 555 coments. I really like this tutorial, it helps me building this circuit every time. Thanks!
you are the best mate thank you.
you put much love for what you are doing and thats great
Thanks for sharing your work !
Awesome! We even have the same o-scope!
Thank you for sharing ic 555 application
Your stuff is Still good! (Noticed a lot of comments have aged) Thanks!
Dear Sir, Great video, I am a student of electronics and your videos are easy to understand and the circuits are very interesting to watch, Keep up the good work, and have a pleasent day.....
Thank you
Very helpful video, thank you!
nice explanation. Thank you for making the vid and sharing.
Man, I love the 7-Ps... may start implementing that at work.
Feel free
Привет порой не знаю как быть етих ответ
Thank you i understanded the fundamental of this, i have been able to make a buzzer with it.
This was great. I was experimenting with a version from my old Radio Shack Engineer's Handbook, by Forest Mimms, and not getting favorable results. I have used the "academic" version, but I was amazed to be able to build this minimalist version, and get precise control over the frequency. With R1 & R2 , being equal I have control over the duty cycle aswell. I also liked the reference to Steve Woznicak. Job's often gets so much of the credit for Apples success, but Woz was the Engineer.
Not quite sure what I’m looking at…BUT I LIKE IT!!!
Good refresh. Thank you sir
nice and simple, thanks
Thank you. I think I will try this.
good stuff. hope you're doing well.
wooked perfectly, thanks
Great! Exactly what I need
Tip: put the speed of the video on 1.25X if you are in a hurry. Good video thx👍🏻
i like how you executed the video, but there is a but, i am going to be making a 555 circuit soon for the first time and im going to use 2 resistors. sadly because i never made this circuit before, and because you used the adjustable resistor in place of r1 and r2, i still dont know how to make the circuit. it kinda sucks cause other than that you would of helped me learn how to build the circuit. thanks for the upload, i still gave a thumbs up.
Bro... you make it so easy for me... Love your technic... kiss !!! ahahah Keep making good video !!
I literally love you
Thanks yo it really helped me
thank you so much....such a nice
thank you very good tutorial!!!!!!!!!!!!
Thank you.
Hi, I have made a monostable multivibrator using 555NE timer ic. What observing is it is getting triggered automatically when some electrical appliances are being switched on or off in the house. So is the 555NE prone to pickup noise or problem is something else. Can you think about it plz if you get time.
Great video! I have been wondering for along time how the Triple nickel works. thanks!
Useful vid...thanks
+J. Clowers Welcome
I'm sure Woz approves! :-)
I would love to see a book with everything it can be used for.
Always give u thumbs up..... Good game...... ✌️Peace
I think it was a day ago I laughed at the “Kiss” 😂 I think I’ll make the nooner tomorrow
If I wanted to have a 30 second delay, what size resistor would I put in there? Or something close to it.
hey Mr Paul, I found many spike voltage (on my oscop) - how to removing the spikes ? Thx in advance
Realy Nice !!!
Thou art a clever buggart!
But who are the 40+ could not's who thumbs down?! 🙄
It's as simple as the flip flop I made to drive two different color LEDS through 2 different clear tubes to simulate a pulse for a kid's haloween mask made from a discarded face respirator. He got props for that. 9V battery tucked inside the respirator. Studs from leather collars, light chain and black paint = happy kid!
I can not express how useful this video was for me. The astable schematic from the 555 datasheet/appnote makes it look super daunting. Can you do a video on how to build circuits from schematics? I've not seen a really good video on how to turn a schematic into a real circuit on either breadboard or perfboard (not PCB)
I very mush like your simple methods but not the hands. When I do video demos I always use a good quality dental tweezers, the one with the curve near the end to place parts or very fine needle nose spring loaded pliers. Then my viewers can see exactly whats going on but so can I. I also find the old solid core color coded, dual pair telephone wire perfect for bread board work. It strips easily and fits well into bread boards. Sling your local phone tech installers installing new phone systems into new buildings and they would happy to give the useless off cuts of bundled cables.
Thanks for your input. My hands are swollen do to congestive heart failure. Ill be dead soon and my hands won't trouble you any more.
Sorry to hear that. Life is a cruel mistress. In youth she fills us with promise then takes it all away. I'm an old fart of 76yrs, worked until 70 then I got the push because I was 42% whole person disabled from work related injury. Now from the mistress I have an electrical problem in my heart, it has a bad habit of missing beats often one in four-five. Next step a pace maker.
I can't believe some people actually gave you a thumbs down. The nerve of some people! But don't let stupid people get you down, thanks for your videos.
Simplest connection is resistor from output pin to capacitor on pin 2
4-8, 6-2...as I recall...
wouldnt it be possible for the potentiometer to have a voltage greater than 1/3 VCC which means it wont set the flip-flop?
In last minute of video you mentioned number 82. What do you mean by that?
Yoooooo man big thank you . Been wrecking my brain for a few days as to how to use 555 timer in a PWM for a 5v motor . Any suggestions on cap size and to add in a mosfet to protect the 555 timer. ?
Dear Mr. learn, the first minute and twenty two seconds were all I needed to subscribe. Tired of wasting time sifting through un-endless blogs of scientific tech gurus and their teachers condescending people trying to self teach . Most usually end up telling you just how impossible the task is and that rummaging through 15- 20 year old electronic trash for pieces is pointless and a waist of time, and the best way is just to go drop 30 to 50 dollars at a store.
Only thing worse is gamers getting all bent out of shape when someone asks a question that reveals they have a pirated version, so they get all huffy about it since they spent 40 bucks on a 8 year old game.
Nice and simple, but be careful not to turn pot all the way so as to short pin 7 with vcc. Discharge transistor wouldnt like that. Standard Astable set up always has resistor no smaller than 1K between pin 7 and VCC.
hey my friend I need to make a square signal that have not any small changes in frequency or pulse width but ics like 555 timer can not be like that and have small changes is there any way???
im new in electronics but if i whant put pwm from Arduino vcc i can adjustment my frequency ???? many thanks u r best !
Excellent video. My question is if it is easy to make a circuit that automatically compensates for voltage drop. Say you have a capacitor charged to 7 volts and your target output voltage is 5 volts. When the capacitor discharges, the voltage drops - is it possible to keep a steady voltage from 7 volts to 5 volts at the output? The output being constant 5 volts. The circuit would have to adjust the duty cycle in relation with the capacitor voltage.
Without getting too deep into it, a big (2200 or 4700mA) cap parallel to the output would keep your voltage steady.
Can you post the buylist on how I can get one?
Yes it's just required for everyone, i want to learn such simple placement of components to create DIY PCB boards, can you simplify with PCB making process of eighter Eagle or Fusion 360 so that i can gain more indepth knowledge to arrange components on PCB Board before making order i wanted to create it hot iron and eaching at home ...
Outstanding thank you one extra Sub to your total
is it possible to adjust the length of the crest and the through of that signal?
I want to try to make the through longer than the crest
That was what he was explaining. You can set the pulse repetition rate (frequency) with the capacitor, and the dwell (% of difference between on time and off time) with the potentiometer. He indicated how simple it would be to have relays change between one component value or another. I will control a throttle with a servo for a HD RC aicraft/heli. It needs two speeds, idle and 2500 rpm. One 555 timer kit plus alternate components, and a double throw relay to switch between alternate values. Signal triggers relay and servo goes to work. Signal stops and servo returns to home position, no load.
Thanks,,,by subur designer engineering
Interesting.
Is this possible with regular resistors? What value would I need and where do I connect them?
Use the frequency formula to determine what resistors to use depending on your preferred output. Put them in place of the potentiometer, with one lead of each resistor on the pin connected to the pin in place of the wiper. If you want to see a drawing of your circuit, look at the schematic at the beginning of the video that he seems the find so complex and confusing. He did exactly what was on the schematic except he eliminated the output indicator led portion. Other than that, he replaced the two timing resistors with the potentiometer and wants gullible people to think that he's a genius.
Excellent tutorial. I have a question for you. we have a pot adjusting the duty cycle.... I'd like to keep that and add a pot to adjust the speed somehow. Is this possible?
GORF I’m sure you could with a variable capacitor. Cheap on amazon
@@mikatomik5532 Yes but those are not usually large in range nor are they usually large in value...but I did think about that.
how can i trigger 555ic using lm358 in monostable mode
nice
