Circuit Documentation

Summary

The circuit in question is designed to interface an Arduino UNO R4 WiFi with an array of peripherals including two IR sensors, a servo motor, and an LCD Display (20x4 characters) with an I2C interface. The Arduino serves as the central processing unit, controlling the servo based on input from the IR sensors and displaying information on the LCD. The IR sensors detect the presence or absence of objects, the servo motor responds to the signals from the Arduino, and the LCD provides a user interface to display data.
