Summary of the Circuit

This circuit is designed to interface an IR sensor with an Arduino UNO microcontroller and includes an LED indicator. The Arduino UNO is used as the central processing unit to read the output from the IR sensor and control the LED based on the sensor's output. The LED serves as a visual indicator and is connected through a 220 Ohm resistor to limit the current.
