For my WoodTech class, I was told to build a finish timer setup for our Pinewood cars. In my setup, I have a laser-photoresistor tripwire to signal the place the car came in. Once that happens, SimpleTimer records the time difference between the cars and sends it to a display via SerialPrint. My problem is that I have only got this setup to work with one lane and I need two. Can someone help me with getting the code to work with two photoresistors? Any help would be appreciated.
You say "SimpleTimer records the time difference between the cars..." That sounds like you would need two detectors to be able to determine the difference. I'm probably not understanding something.
Maybe you could describe your setup more completely and then we can help.
