@tasasaki it isn't a consistent note. It sounds like they keep interrupting each other.@UKHeliBob I have bananas hooked up as sensors. each power supply runs through a resistor and then to the analog port and a banana. when the banana and a ground are touched, the voltage to the analog sensor drops. The analogRead() goes from 1023 to around 600. the exact number varies. Thanks for the arrays tip
Try connecting the banana directly to a pin that in setup() you mode as INPUT_PULLUP.
And change those int variables that will never get outside of 0 to 255 into bytes.
