Summary of the Circuit

This circuit is designed to interface an Arduino UNO with various components including an IR sensor, a buzzer, a KY-019 Relay module, multiple LEDs, a gearmotor, and power sources. The Arduino UNO acts as the central controller, managing input from the IR sensor and controlling the state of the LEDs, the buzzer, and the relay, which in turn controls the gearmotor. The circuit is powered by 5V batteries connected to the components requiring power.

Component List

Arduino UNO

• Microcontroller board based on the ATmega328P
