Controlling the Train Elevator Part 3 - Coding

Programming the Arduino Uno for a model railroad elevator control system. The elevator transfers trains between layout levels; the control system prevents the trains from falling off the elevator. Episode 1 of this series demonstrated the prototype and explained the logic. Episode 2 showed the control system parts and wiring. This episode shows how to setup and to code the Uno, plus tips on installing the finished system.
