Hello, I was wondering, how can you control a standard servo by using just 555 timer? Well I got the servo to jiter a little and some what make it move, but what would be the correct frequency to general a smooth left and right motion of the servo? Thank you in advance smile.gif

    The frequency should be close to 50 hz, to get a smooth movement you have to smoothly vary the duration of the pulse. The link in my sig is to a 555 based servo tester, you can find a schematic there.
