This is the simple basic design of servo motor controller with pulse generator. It uses the CMOS IC 7555 in the Astable mode to generate pulses to drive the servo motor. The circuit can be suitably ...

There’s nothing quite like a nice, simple hack. This serial servo controller uses a PIC12C671 and a pair of resistors. Leaving out the power supply, that’s the lowest part count I’ve ever seen.

This is sort of a follow up to the diy A/C zone control post. It’s a pretty simple circuit, but now they’ve posted schematics for building your own 1-wire controlled servo actuators. It requires ...
