Introduction: 47 Projects to Do With a 555!

Picture of 47 Projects to Do With a 555!

These are a whole bunch of things to make with the 555 timer IC with a note for each picture.
I do not take credit for these schematics, they were made by Collin Mitchel.

As you would probably think it took me a very long time to make this but it was night and i was wanting to waste some time so i hope you like it!

I have descriptions for each and every picture so feel free to ask questions!

Wonderful treasure

All these circuits were drawn by me: COLIN MITCHELL
See my website: talking
and 555 circuit eBook with descriptions of the circuits

mr Collin,

Thank you so much sir.

i just dloaded your book, and will try it out.


georgelstuart (author)colin552012-11-17

Colin, I recognized your drawings immediately and wanted to point out this author's source from which the drawings were shamelessly copied, then saw that you already did, and it seems that nobody cares... the dark side of open sharing I guess... at least the link you gave will expose your generously informative website to some new readers.

Actually I emailed him and asked permission to use these schematics which he allowed.

J-Five (author)Jimmy Proton2016-10-01

And you did give him credit.

MROHM (author)colin552013-06-26

Thanks Colin,,, Awesome designs you have here!!!! Unfortunately the Designer of the 555 chip Hans Camerzind passed away Recently,,His Design of The 555 chip made it a Household Name!!! The 555 is still one of the most widely used I.C.chips in the history of I.C. electronics!!! Actually with all the circuits we have here I Don't know which one I want to Breadboard Here!!!

Mr. Colin55
My name is Mike
I have a question or a favor for you maybe you can help me. Thanks in Advance
I am in the process of making a board game called shut the box it's a dice board game. I'm sure you have heard of it for my daughter. Instead of flipping wooden numbers I would like to use some type of ic numbers 1-9 that are fixed so all I have to do is push a button coresponing to the specific number to turn it on or off if you look at google images under shut the box to get a better idea of what im talking about. any help would be greatly appreciated you can email me at
thank you so much

555 timer pulsed radio fm jamer.

SHOE0007 (author)2017-02-01

You should include a 555 timer attached to an Op amp as a amplifier and pulse it through a coil.

most the circuit given in above article works , i presonally made 60 % of circuit and its really a great fun ,so i decided to make each project and write an article for students so that they can learn and use for their projects ,reports

These circuits copied and posted here... you should not claim circuits as yours when you did not design them.

J-Five (author)ol FERAL lo2016-10-01


He didn't. He clearly stated were he found them ( even gave the website) and who made them, if you read the introduction.

please provide me details of switch plate, switch on off and HEE HAW SIREN.

my email is

ol FERAL lo (author)JavedJ12016-03-17

go to

and see all these circuits and more with details given by the real designer.

igrewold (author)2015-12-08

Dude you shoulda LINKED to the source!

MohammadA9 (author)2015-01-03

what program used to make these circuits

plz help

igrewold (author)MohammadA92015-12-08

try Fritzing, it is nice and free, also gives three types of how circuits are drawn:

SaeedH1 (author)MohammadA92015-07-10

use circuit wizard , that the best software for making 555 timer projects visit

Use diptrace

MohammedS59 (author)2015-11-18

i love this

HoW to use the tv remote jammer

ponchbelly made it! (author)2015-05-01

I built the toy organ and substituted a photo detector (5k - 500K ohm) instead of the pot. I had a ton of fun moving my had up and down to change pitch and used the other hand to control the tactile buttons. Well done!

can any one help metal detector with 555 timer

hello ,I am in the process of making in this CKT

pwamutitu (author)2013-07-27

hallo i need to make an led signboard with as many led's as possible. probably 500. how can i drive the leds using 555 and 4017 without compromising on current. what would be the ideal voltage. reply

LedDiodeSVK (author)pwamutitu2014-09-01

Oh man, if you want to drive MORE than 500 LEDs by 555 and 4017, you nedd REALLY MUCH soldering and contruction. Use MCU, its easier and you can take it what you want. But you probably will need multiplexer. Just use think called google.

Hello Guys, I am facing difficulty in finding good microphone for sound operated robot with 555, I purchased many mic. phones but its range is very. How could I amplify n improve its range? please suggest me the best one.

ajay.tornado (author)asamudrala2014-07-27

get a wireless mic and provide a receiver to the robot.

jensenr30 (author)2013-01-09

wow! this is one 555 timer instructable that I can really get behind!
I find that most of them are way too many describing how to do the same thing. but you have really done a neat thing putting all of these different projects together!

I like it.

Lucky7x7 (author)2012-11-17

You have sensitive touch switch twice... : ) only because you asked

~CableGuy (author)2012-11-15

man just,... W.O.W!, GREAT! (+ 100 other positive words)

EA ready (author)2012-09-13

I need help with coming up with a circuit or finding one that will operate a remote control car to 22 feet then cut off. If anyone have any ideas or can point me in the right direction it will be appreciated!!
