Summary of the Circuit

This circuit is designed to interface an Arduino 101 microcontroller with multiple IR sensors and an LCD I2C display. The Arduino 101 serves as the central processing unit, reading inputs from the IR sensors and displaying relevant information on the LCD. The IR sensors are used to detect the presence or absence of objects, and the LCD display provides a user interface to display the sensor readings or other messages.
