Arduino, CMRI and JRMI - Part 3 - Multi Node CMRI Networks

Part 3 of 3 in a series on using Arduinos as CMRI nodes and controlling them in JMRI. In part one we setup sensor inputs and servos on the Arduino and in part 2 we added outputs (servos, lights, motors, etc.). In this video we create a CMRI network that can support multiple CMRI nodes from a single USB connection. This allows you to put nodes closer to where sensors and servos are required and saves on wiring.
