Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller, an HC-SR04 Ultrasonic Sensor, and a Micro servo 9G. The Arduino UNO acts as the central processing unit, controlling the servo motor and reading distance measurements from the ultrasonic sensor. The servo motor is powered and controlled by the Arduino, and the ultrasonic sensor is used to detect objects within a certain range by emitting ultrasonic waves.
