I need to find a way to make a servo motor (from RC model building) first move in one direction, and then after it stops, go back to neutral.(without a model building receiver and Control)This has to be connected to an Impulse-button and should not be wireless. Is there any IC I could use, and how?
I agree w/JFDuval, but I would probably use 2 555's (or 1 556). Use one of the 555's to generate a 50Hz signal and the other to give the appropriate pulse width the servo needs to turn.
Here's a link for a page which might help:
It's a short tutorial on how the servos operate. They're quite easy to work with.
