UNOs Drive Trains

“Claremont Road” has five Arduino UNO microcontrollers which control train movements, along with PWM (servo adapted) points/turnouts, and signals according to pre-written programs or “sketches”. This is a completely different concept from DCC.

 

The master co-ordinating UNO gets feedback from the track through 14 enbedded infra-red proximity detectors,

 

Slaves 1-3 are UNO “train drivers”,

 

Slave 4 handles the display and lights. The orange display shows the current mode and commands being passed between the UNOs via a short-wire protocol known as I2C.
