Circuit Documentation

Summary

This circuit consists of an IR sensor, a 4-channel relay module, a buzzer, an L298N DC motor driver, and a 6xAA battery pack. The IR sensor detects an object and triggers the relay, which in turn activates the buzzer. The L298N motor driver is powered by the battery pack and can control DC motors.
