![]() The basics and composition of an SG90 will be explored, and the application of several servo codes and applications will be given for another type of servo motor, the MG90S. In this tutorial, an Arduino board will be used to power and control a small servo motor. Lastly, servo motors use a circuit to control and send feedback information to a given controller, which in our case is an Arduino board (read more about servo motors here). Often, servo motors contain a series of gears that either speed up or slow down and smooth the movement of the DC motor. The low-cost servos that are found in maker projects use potentiometers to register voltages as positions on the rotating plane of the servo. ![]() ![]() Servo motors are often comprised of DC motors that use feedback mechanisms to move with great precision from one position to another. Servo motors can be found in robotic arms, cameras, lathes, CNC machines, printing presses, and other engineering applications where precision and repeated movement are required. ![]()
