Starting with a "dumb" application to send a command to the rest of TrainThing. Need this to test coding of command processing by the Raspberry Pi (3).
Configure TrainThing Hardware
Configure Wabbits that control switches, part of the layout (1)
Configure Arduino (2)
IR Sensor Inputs
Relay Control Outputs
Train Addressing
Configure Raspberry Pi 4 (3)
Semaphore signal to Servo address
Semaphore signal aspect to servo angle
semaphore signal to Unicorn X,Y coordinates
Associate switch state sensor ID with IOPi bus/pin
Configure Raspberry Pi 3 (3A)
Associate switch state sensor ID with Raspberry Pi GPIO pin
