Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller, a servo motor, a pushbutton, two LEDs (red and green), and two resistors. The Arduino UNO controls the LEDs and the servo motor, while the pushbutton is used as an input device. The resistors are used to limit the current through the LEDs.
