Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller, a servo motor, and a power supply. The Arduino UNO is programmed to control the servo motor, making it sweep from 0 to 180 degrees and back continuously. The servo motor is powered by a 5V power supply, which also provides power to the Arduino UNO. The ground connections are shared among all components to complete the circuit.

This code is designed to run on an Arduino UNO microcontroller. It initializes a Servo object and attaches it to pin D3. In the main loop, the servo is instructed to move between 0 and 180 degrees in a sweeping motion. The delay(15) function call ensures that the servo has enough time to reach the desired position before moving to the next one.
