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. - Věda a technologie
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 ?

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 ...
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
‘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.
The best 555 explanation ever.
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.
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!!!
This is the best channel for learning electronics, Paul is such a cool guy
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.
Thanks Paul really enjoying your videos. They make electronics much clearer than 28 years ago when I was an engineering student.
I enjoyed it and learned something USEFUL!! Minimal bits to do the job. Gratitude!
"This is good, it's academic, it's to much". Got me tuned in ❤
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.
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.
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.
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 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.
SORRY I AM FRENCH. SO MY ENGLISH...... POOR. IT IS THE BEST DEMO I NEVER SEEN ABOUT 555. THANK YOU.
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.
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!
Absolutely brilliant, simple and practical explanation mate. Thanks heaps!
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"
Great tutorial and ingenious breadboard layout
Great video, you just made it easy and fun to set up my very first 555 timer. THANKS A TON!!!!
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.
Woz is the man.
@@learnelectronics I really enjoy your presentations. I am in my final year as a student of electrical engineering, and your videos help me to get back to in tune with why I chose this path. The passion for experimentation.
Very cool video with the 555 basics!
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 😊😊😊
Perfect...exactly what i was looking for. Thanks for sharing!
The first chip I ever used while I was still an apprentice (late 70's)! Like me still going strong(ish)!
+gartmorn nice!
Love these simple circuits. Great for learners like me
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.
Excellent 555 lesson. Thank you for sharing.
So simple I got it to work on the first try thax man!
Very nice detail video. Thanks for sharing.
Thou art a clever buggart!
But who are the 40+ could not's who thumbs down?! 🙄
Tried various circuits. This was the first one to work!
Thanks for sharing your work !
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
Nice video! Thanks for teaching
Very straight forward - thanks
Man, I love the 7-Ps... may start implementing that at work.
Feel free
Привет порой не знаю как быть етих ответ
you are the best mate thank you.
you put much love for what you are doing and thats great
Very helpful video, thank you!
This video has 555 likes, it should have 555 coments. I really like this tutorial, it helps me building this circuit every time. Thanks!
nice explanation. Thank you for making the vid and sharing.
I love this guy! Amazing video
Tip: put the speed of the video on 1.25X if you are in a hurry. Good video thx👍🏻
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.
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!
Thank you for sharing ic 555 application
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!
Good refresh. Thank you sir
Not quite sure what I’m looking at…BUT I LIKE IT!!!
Your stuff is Still good! (Noticed a lot of comments have aged) Thanks!
Bro... you make it so easy for me... Love your technic... kiss !!! ahahah Keep making good video !!
nice and simple, thanks
I think it was a day ago I laughed at the “Kiss” 😂 I think I’ll make the nooner tomorrow
Thank you. I think I will try this.
Thanks yo it really helped me
Great! Exactly what I need
good stuff. hope you're doing well.
wooked perfectly, thanks
thank you so much....such a nice
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.
thank you very good tutorial!!!!!!!!!!!!
Good God. I'm glad it's simplified. But I can't for the life of me figure out these things. I'm trying to build a simple circuit, so I thought...i want an LED to blink for a set amount of time, after a photo resistor sees light. Lol, sounds easy enough. Totally isn't seeming to be.
Keep practicing, it does get easier - I promise!
@@dandoo111 yep...i got it!
I literally love you
Useful vid...thanks
+J. Clowers Welcome
Always give u thumbs up..... Good game...... ✌️Peace
Realy Nice !!!
Great video! I have been wondering for along time how the Triple nickel works. thanks!
How to make KISS impersonal: keep it stupid simple
Great presentation but for the guy who first heard of a 555 circuit 8minutes ago please explain what this is and why it exists
Try looking up ben eater's video on the stable or astable 555 timers. He actually walks through the chip logic and explains the triggers and cap/resister maffs. Simply search monostable or astable.
It's a timer with 3 different behaviors. Single shot, bistable, and astable. It can be adapted to be a clock, a switch, a timer, an audio source, etc..
Thank you.
I would love to see a book with everything it can be used for.
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. ?
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.
The formula is actually F = 1.44 / (R1 + 2R2) C..
I'm sure Woz approves! :-)
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 though frequency is f= 1.44/(R1+2R2)C1. Is there a reason the 2 was left out or am I wrong
You are not wrong. Thanks for pointing it out.
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.
Outstanding thank you one extra Sub to your total
great !!! nice...
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.
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.
I subbed.
im new in electronics but if i whant put pwm from Arduino vcc i can adjustment my frequency ???? many thanks u r best !
can you switch the 20k potencometre to a simple resistor ?
You can, but you will need another resistor to complete the divider.
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 ...
nice
man, I don't get it...I've put together way more complicated circuits, but failed to build this 3 times. Found your video, followed along. bingo bango. thanks for your assistance.
What IDE do you use. Like I have said before I’m new to this so I’m trying to get correct info and direction from individuals like you and your group for guidance. Anything you can recommend is greatly appreciated. Thanks again your videos are excellent. Artie 😊😊😊
IDE, I just use the latest from Arduino
learnelectronics thank you for getting back to me so promptly much appreciated. 😊😊😊.
Loved the video man! Just wondering where to connect the output (say a motor or led) to the breadboard??
Pin 3
@@learnelectronics Thanks, I should have realised that from the video🤦😂
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?
