Neopixel on Dashers TBC OUTPUT Neopixel serial
Cherry/olive conveyor TBC OUTPUT pulse low
Lemon vendor TBC OUTPUT pulse low
Stirrer TBC OUTPUT pulse low
Umbrella dropper TBC OUTPUT pulse low
Big Syringe TBC 2 x OUTPUTs both need to support PWM
Platform "glass present" TBC INPUT_PULLUP 0 = no glass, 1 = glass present
Platform illumination control TBC OUTPUT serial (TX to platform only)
Pololu stepper controller TBC 3 x OUTPUTs Step, Direction, Enable
Limit / zero switch TBC INPUT_PULLUP 0 = platform at zero, 1 = platform not at home position
Emergency stop TBC INPUT_PULLUP 0 = switch pressed, 1 = switch not pressed
Lighting / bling ? ? ? Neopixel serial?
Serial comms to/from Rassberry Pi 1 x INPUT, 1 x OUTPUT serial (TX / RX)
Total I/O 27 x OUTPUT, 3 x INPUT_PULLUP, 1 x INPUT
