Circuit Documentation
Summary
This circuit consists of an Arduino 101 microcontroller, a sound sensor, and a piezo speaker. The sound sensor detects audio levels and sends an output signal to the Arduino, which processes the signal and can trigger the piezo speaker to emit a sound. The Arduino 101 is powered by a 5V supply, which also powers the sound sensor. The piezo speaker is connected to one of the digital pins of the Arduino for signal output and to the ground for completing the circuit.

Documented Code
No code has been provided for the microcontroller. To operate this circuit, code must be written and uploaded to the Arduino 101 to read the signal from the Sound Sensor and control the Piezo Speaker accordingly. The code should include functions to initialize the pins, read the sensor data, and output the appropriate signal to the Piezo Speaker.
