Summary

This circuit is designed to control an AC bulb using a sound sensor and an Arduino UNO. The sound sensor detects sound levels and sends a signal to the Arduino, which then controls a relay to turn the AC bulb on or off. The circuit is powered by a 9V battery connected through a power jack.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your variables and settings, and the loop() function is where the main code runs repeatedly. In this circuit, you would add code to read the sound sensor and control the relay based on the sound levels detected.
