47 Projects to Do With a 555!

Introduction: 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!

Can any one explain the working of traffic light with two 555 based on mode of operation of 555

0

So the left 555 times the Red LED when pin 3 is low which resets the right 555 pin 4.

When the Red LED times out pin 3 goes high which allows right 555 to start timing by first pulling pin 7 momentarily low (normally to discharge a timing cap) which causes the Orange LED to light followed by pin 3 going high turning Green LED On...

Until the right 555 times out Green goes off as pin 3 goes low and the Orange LED goes on as pin 7 low goes to discharge..

Then sometime later the left 555 times out pulling its pin 3 low

turning on the Red LED On and resetting the right 555 ...

mr Collin,

Thank you so much sir.

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

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.

And you did give him credit.

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 mag200181@gmail.com
thank you so much

555 timer pulsed radio fm jamer.

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

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

Hello!!!!

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.
