Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with a Micro servo 9G and an HC-SR04 Ultrasonic Sensor. The Arduino Nano serves as the central processing unit, controlling the servo's position based on input from the ultrasonic sensor. The ultrasonic sensor is used to measure distance by emitting ultrasonic waves and measuring the time it takes for the echo to return. The servo motor is controlled via PWM (Pulse Width Modulation) signals from the Arduino Nano, which allows for precise control over the servo's position.
