The most simple way to set up a 555 timer 

LOL, You just made the 555 a pile more friendly to me .. Thank You.

There should be a 555 fan club. Everyone loves it.

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.

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.

‘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.

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!!!

I enjoyed it and learned something USEFUL!! Minimal bits to do the job. Gratitude!

Thanks Paul really enjoying your videos. They make electronics much clearer than 28 years ago when I was an engineering student.

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.

This is the best channel for learning electronics, Paul is such a cool guy

I love your videos man. I was having so much trouble actually getting output from the 555 before this.

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.

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!

It's amazing how after 40+ years the 555 is STILL such a versatile IC

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.

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..

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.

Absolutely brilliant, simple and practical explanation mate. Thanks heaps!

The best 555 explanation ever.

Great video, you just made it easy and fun to set up my very first 555 timer. THANKS A TON!!!!

"This is good, it's academic, it's to much". Got me tuned in ❤

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 😊😊😊

Thanks - that is what I needed- just a simple explanation, not some MIT bint going off on comparators and shite that go beyond me!

Very cool video with the 555 basics!

Perfect...exactly what i was looking for. Thanks for sharing!

Great tutorial and ingenious breadboard layout

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 AM FRENCH. SO MY ENGLISH...... POOR. IT IS THE BEST DEMO I NEVER SEEN ABOUT 555. THANK YOU.

Excellent 555 lesson. Thank you 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!

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.....

Love these simple circuits. Great for learners like me

So simple I got it to work on the first try thax man!

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.

you are the best mate thank you. you put much love for what you are doing and thats great

Man, I love the 7-Ps... may start implementing that at work.

Nice video! Thanks for teaching

The first chip I ever used while I was still an apprentice (late 70's)! Like me still going strong(ish)!

Very straight forward - thanks

Very nice detail video. Thanks for sharing.

Tried various circuits. This was the first one to work!

Your stuff is Still good! (Noticed a lot of comments have aged) Thanks!

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.

Thanks for sharing your work !

nice explanation. Thank you for making the vid and sharing.

I love this guy! Amazing video

Very helpful video, thank you!

Thank you for sharing ic 555 application

Thank you i understanded the fundamental of this, i have been able to make a buzzer with it.

Awesome! We even have the same o-scope!

Not quite sure what I’m looking at…BUT I LIKE IT!!!

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.

Good refresh. Thank you sir

nice and simple, thanks

Bro... you make it so easy for me... Love your technic... kiss !!! ahahah Keep making good video !!

In last minute of video you mentioned number 82. What do you mean by that?

Tip: put the speed of the video on 1.25X if you are in a hurry. Good video thx👍🏻

Thank you. I think I will try this.

Thou art a clever buggart! But who are the 40+ could not's who thumbs down?! 🙄

If I wanted to have a 30 second delay, what size resistor would I put in there? Or something close to it.

wooked perfectly, thanks

Great! Exactly what I need

Great video! I have been wondering for along time how the Triple nickel works. thanks!

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. ?

good stuff. hope you're doing well.

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.

hey Mr Paul, I found many spike voltage (on my oscop) - how to removing the spikes ? Thx in advance

Thanks yo it really helped me

thank you so much....such a nice

wouldnt it be possible for the potentiometer to have a voltage greater than 1/3 VCC which means it wont set the flip-flop?

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.

im new in electronics but if i whant put pwm from Arduino vcc i can adjustment my frequency ???? many thanks u r best !

thank you very good tutorial!!!!!!!!!!!!

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???

Useful vid...thanks

Can you post the buylist on how I can get one?

I literally love you

I though frequency is f= 1.44/(R1+2R2)C1. Is there a reason the 2 was left out or am I wrong

how can i trigger 555ic using lm358 in monostable mode

Is this possible with regular resistors? What value would I need and where do I connect them?

what is it use for? and how would i connect it up? ok! just found anther one of your videos "555 timer fun" hope this will answer the question.

Realy Nice !!!

I would love to see a book with everything it can be used for.

Thank you.

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!

Hello, awesome video. really explained and helped me understand. but one thing i didnt quite get was the resistance values in the frequency equation. were those the trimmer? sorry if im asking dumb questions, im relatively new at electronics.

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?

Great video of how to make an Astable circuit. Can you do this for the Monostable circuit too? I would like to build a timer which cuts off power after a few seconds after a button has been pushed to save some energy for long time dash buttons built out of ESP8266 or ESP8285 and not using the sleep mode.

Loved the video man! Just wondering where to connect the output (say a motor or led) to the breadboard??

Great thanks for the simplification! Is there such a thing as a variable capacitor? Then u can adj freq and duty cycle.

Always give u thumbs up..... Good game...... ✌️Peace

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

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 think it was a day ago I laughed at the “Kiss” 😂 I think I’ll make the nooner tomorrow

I'm sure Woz approves! :-)

Hi, is it absolutely necessary to connect pin 4 to Vcc? Thank you!

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.

can i drive an ignition coil with a mosfet switching off pin 3? I waant to build an ignition coil tester with a 555.
