I
found some very slick Arduino IR Detectors on eBay at a very good price
and I figured that they would be worth the investment of 45¢ to play
with, 10 for $4.50.
They turned out to be very good for under the track type obstacle detectors. So good I decided to give Geoff Bunza’s Crossing Gate Controller a shot. The detectors and the Arduino Sketch work great!
