Summary of the Circuit

This circuit is designed to interface an Arduino UNO with an HC-SR04 Ultrasonic Sensor and a Servo motor, powered by a Polymer Lithium Ion Battery. The Arduino UNO acts as the central processing unit, controlling the Servo motor based on distance measurements obtained from the HC-SR04 Ultrasonic Sensor. The Polymer Lithium Ion Battery provides the necessary power to all components in the circuit.
