I am trying to create a drag tree that will really work with electric eyes (like from a garage door sensor). I actually want 8 "starting gates" that are all linked to 4 light trees and eight electric eyes so that 8 racers will be monitored for red light starts. Is this even possible? Its for jet ski racing...the 4 light trees will have to be in sync. I Dont need pre-staging and staging. but need the normal progression to green and then the ability for 8 electric eyes to work for redlights of the 8 racers.
I'm new here. I know nothing! Somebody recommended me come on here to see if anyone here would like to take a crack at it. He told me "You would be using the light controller in conjunction with an Arduino that would take you garage door sensor inputs and compare it to the light controller to tell you who red lit. "
I don't have a light controller or any other hardware for that matter. I was hoping someone here would tell me what to get and how to make it and what to do to use it.
This is the guy I started with:
