The circuit in question is designed to interface an Arduino Leonardo with various sensors and a motor driver to control a DC motor. The sensors include PIR motion sensors, limit switches, and an HC-SR04 ultrasonic distance sensor. The Arduino Leonardo is responsible for processing the inputs from these sensors and controlling the motor driver, which in turn controls the DC motor. The circuit is powered by a DC power source.

connected to IBT-2 H-Bridge Motor DriverThere is no code provided for the microcontroller. The code would typically include initialization of the input/output pins, reading sensor states, implementing control logic for the motor based on sensor inputs, and handling timing for the ultrasonic sensor measurements. Without the code, the specific functionality and behavior of the circuit cannot be documented further.
