Tiny Servo Controller

Servo motors are common choice where mechanics is involved. These may be robotic claws, door locks or simply RC models. As you may know in order to make servo motor turn you need provide a PWM signal with changeable duty cycle. This is where microcontrollers are good at. Anyway if you finished your mechanical part of project and want to test how it works you need a controller which may not be finished. This is where this mini servo controller becomes handy.

Dilshan built a PIC based mini servo controller which which may be used to drive most popular servos. It has two control interfaces – analog where servo can be turned by changing pot value; and digital where servo is controlled with push buttons. PIC12F675 takes care of generating correct PWM upon control signals.
