I hope this is the right place for this, go ahead and tell me to go away if it's not. I'm using four piezo buzzers as "knock" or "impulse" sensors, sending each into a different analog pin. I've attached a wiring diagram. The goal is to be able to detect which buzzer, of the four, gets hit. Unfort…

Is it possible to set an analog pin low and digital until the instant you want to read it set it analog read the pin and set it low again?
