Servo Motor Control for Model Railways Part 3 of 3 - Semaphore Signals

This is the final video 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 and signals such as using digital accessort decoders, capacitor discharge units (CDUs) and solenoid motors.
