excuse my ignorance in the field of arduino. I recently bought pclapcounter and I wanted to make it work with an arduino one, my track is a 4-lane niche, what I need is a protocol to manage the 5 red lights plus a green, the arduino relay card to activate the current on the track at the start of the race, and the detection of the revolutions by photodiodes. does any of you know how to do it? and if I do not ask much, can I have a protocol and a link scheme? thank you so much
