Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with multiple Piezo sensors and a Tower Pro SG90 servo motor. The Arduino Nano serves as the central processing unit, interfacing with the Piezo sensors to likely detect vibrations or pressure changes. The servo motor is controlled by the Arduino, which provides the signal and power necessary for its operation. The circuit is powered by a 4xAA battery pack, which supplies power to the Arduino Nano and the servo motor.
