Good Day Everyone.
I'm John and I am a novice at code
It seems that somehow, I have my sensor triggers going to Analog side of my Arduino and I think I need to use or would like to use the digital side like 9 and 10 to possibly increase the sensitivity of my infrared sensors.
I just don't know how far down or how many line down the sketch I need to change I will send a copy of my sketch.
another set of eyes would be greatly appreciated
Thanks,
John D
