Model Railway Sensors & Detection Part 2 - Train Detection and Automation with IR Sensors

A step by step guide to adding sensors to your layout using an Arduino and JMRI. Adding sensors is the first step in automation and can be used to control trains, signals and points. Part 1 - we build the sensor hub and connect an infrared (IR) sensor. This can be used to provide feedback from analogue or digital layouts.    • Model Railway Sensors & Detection Part 1 -...   Part 2 - we use two IR sensors to automate a train controlled by JMRI on a digital layout.

I have uploaded these files to my GitHub area (https://github.com/LittleWicketRailwa..., but all credit should still go to Geoff Bunza for developing this system. This is a simple way of adding sensor to a layout, but I would encourage anyone interested in this to explore the CMRI video series which uses the same hardware, but allows use of different sensor names, doesn't require a script to be run in JMRI and can be adapted to change inputs to outputs.
