Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller board interfaced with a Tower Pro SG90 servo motor. The Arduino UNO is programmed to control the position of the servo motor by sending it a series of pulse-width modulation (PWM) signals. The servo motor is powered directly from the Arduino's 5V output and is controlled via one of the Arduino's digital I/O pins.
