Summary of the Circuit

This circuit is designed around an Arduino UNO microcontroller, which serves as the central processing unit. The circuit includes two IR sensors for detecting objects or movements, a servo motor for actuation, and an LCD I2C display for user interface and data display. The Arduino UNO is responsible for controlling the servo based on inputs from the IR sensors and displaying relevant information on the LCD screen.
