Can anyone here help me figure this out. Need to setup two IR beams that when broken will trigger a relay of some sort.
Here is what I'm doing, trying to build a timer for a local mud truck rally. the track is setup like a drag strip and is 100 foot long. I found a setup where they used a hand held stop watch with a switch wired to the start and stop button of the stop watch. Pretty simple, but I need the switch to be the IR beams spanning the start and finish line with a 2 second delay so it wont turn the stop watch off when the rear tires brake the beam.
Thanks Steve............
