I was just given 6 IRDOT-1. I would like to hook these up to create a simple system. Train does over IF, signal changes from green to red.
How do I do this.

One our members uses a lot of IR detection. The IRDOT, I gather has the detector in the middle of the circuit board.
Directions: http://www.heathcote-electronics.co.uk/how_infra_red_model_train_detection_works.html
Directions part 2, this says the emitter and detector are attached by 18" wires, which would be more useful, in my opinion
Depending on how you’re using the IR detection I would suggest using the Arduino FC-51.
I have cut over to the FC-51 exclusively. They don’t meet their advertised specs of 30CM but work reliably up to 6”. Can’t beat the price on eBay of under 50¢.
I have extended the sensors as much as 4’ with out any problems. The sensors have standard .1” leads so the micro header strips work great for connectors. I have several working on four conductor ribbon wire.
I made a jig for drilling holes between Atlas HO code 83 track.
It should read Simple Signal System
They will reflect off almost any surface at 4”. Mine are reflecting off the bottom of the locomotives and rolling stock. It gives you a 5 volt logic low when something reflects the IR emitter beam back to the IR sensor.
They can also be used for beam break too but that reverses the output, the output is low until the beam is broken. Working as beam break it works easily at 20’.
