Hello all,

I had an Idea recently for a robot. It is very simple, as it only requires a servo to move forward and back. I have had trouble finding any information as to how to interface something like a H-bridge with the Arduino. Can anyone help please? Thanks.

You don't use an H-bridge for a servo.

You can use the Servo library to control a bunch of servos: http://arduino.cc/en/Reference/Servo

Unless he is talking about a real servo motor and not a hobby servo. In motion control and industry servo means something quite different.

How big a motor? Do you have any existing controllers for that motor?

And yes. Normally an H-Bridge is used to control a DC motor. What voltage and current rating is your motor? Does it have an attached encoder?
