I have a few (three) servos that have faulty circuit boards. I want to repair them by replacing the circuit board with a new (PICAXE) one.
I thought I would use an 08M reading the sinal via pulsin. It would then readadc the position of the potentiometer, then move the motor accordingly, via some driver. I would slow the motor using PWM when the potentiometer gets near its wanted position.
I thought I could also add features such as failsafes (when you first plug in the servo, the incoming signal is stored as the failsafe setting).
The whole project will be done in SMD components.
I would like feedback on:
- Any other features that would be useful (eg EPA?)
- A good H bridge driver for one motor that can provide the current needed (+1A?). Preferably the driver would be for one motor only, so I can keep both costs and size down.
