I have a phototransistor and an LED, when I test in Arduino I do get readings from the phototransistor, but when trying to get the same readings in Processing I just get continuous 0’s. Can any one help? I’ve placed the code below. The phototransistor is connected to port A1. Thanks! import cc.ardu…
