Summary of the Circuit

This circuit integrates an Arduino UNO microcontroller with a Micro servo 9G and an HC-SR04 Ultrasonic Sensor. The Arduino UNO serves as the central processing unit, controlling the servo motor and interfacing with the ultrasonic sensor to measure distances. The servo motor is controlled via PWM signals from the Arduino, and the ultrasonic sensor is used to detect objects within its range by emitting ultrasonic waves. The circuit is powered by the 5V output from the Arduino, which is distributed to both the servo and the ultrasonic sensor.
