Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with a TSOP312 IR receiver and a two-channel 5V relay module to control two bulbs. The circuit is powered by a 9V battery. The IR receiver allows the Arduino to receive infrared signals, which can then be used to control the relay module, switching the bulbs on or off. The relay module acts as an electrically operated switch that can handle the high current required by the bulbs, which are powered separately by the 9V battery.
