Servo Motor Control for Model Railways Part 2 of 3 - Servo Point Motor

This is the second part in a three part guide on how to connect servo motors to an Arduino and control them using JMRI in order to throw points or operate semaphore signals on a model railway. This will work for both analogue and digital layouts and is a step towards layout automation. It's also very cheap compared to other methods of operating points such as using digital accessort decoders, capacitor discharge units (CDUs) and solenoid motors.
