Circuit Documentation

Summary

The circuit in question is designed to interface an Arduino UNO microcontroller with a set of peripherals including two IR sensors, a servomotor (SG90), and an LCD Display (16x4 I2C). The IR sensors are used to detect the presence or absence of objects, the servomotor to actuate based on sensor inputs, and the LCD display to provide a user interface or feedback. The Arduino UNO serves as the central processing unit, controlling the sensors, the motor, and the display.
