When I run the "blink" program, the LED turns on and off like it should. However, when I run the "Knock" program, it stays lit but flickers when the piezo is knocked. Why is it staying lit? Thanks! const int led = 1; // led connected to digital pin 1 const int piezo = A0; // the piezo is connected…

Why does this LED stay ON?
