can't find a single functional 555 circuit
« on: November 07, 2009, 07:56:47 PM »
i don't know why this is but none of the 555 circuits i find seem to work. i've replaced the 555 several times and i still can't get it to work. can someone give me a 555 led flasher circuit that they KNOW works so i can test it out? i must be doing something wrong but since all the diagrams i see look completely different and some even look like they short circuit themselves.

Post a couple of links to what you cannot get to work.
Some of the circuits on the net is not working. but if you have tried several, I assume you are doing something wrong.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
