Summary

This circuit integrates an Arduino UNO microcontroller with an infrared (IR) sensor and a red two-pin LED. The Arduino UNO is used as the central processing unit to interpret signals from the IR sensor and control the LED based on the sensor's output. The IR sensor is powered by the Arduino and its output is connected to one of the Arduino's digital pins for signal processing. The LED is used as an indicator and is connected to another digital pin on the Arduino for control.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
