This sketch reads a piezo element to detect a knocking sound. It reads an analog pin and compares the result to a set threshold. If the result is greater than the threshold, it writes "light switch on!" to the serial port, and toggles the LED on pin 13.

1. First function active when piezo got hit.
2. Second function send singnal to 120V power relay and lit up two light bulbs in real time.
