Arduino Servo Motor Controller

Now let s see how to use an arduino to control a servo motor.

Arduino servo motor controller.

The guts of a servo motor is shown in the following picture. In this tutorial an arduino board will be used to power and control a small servo motor. The library can control 12 servos using only 1 timer. 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.

As a result s ervo motors are used to control the position of objects rotate objects move legs arms or hands of robots move sensors etc. One is for power 5volts ground and the white wire is the control wire. For most servos a 1 ms pulse results in a zero degree rotation a 1 5 ms pulse results in a 90 degree rotation and a 2 ms pulse results in a 180 degree rotation. You can also see the 3 wires that connect to the outside world.

Because servo motors use feedback to determine the position of the shaft you can control that position very precisely. You can connect small servo motors directly to an arduino to control the shaft position very precisely. Following are the steps to connect a servo motor to the arduino. You can see the control circuitry the motor a set of gears and the case.

The goal of this project is to intro. Allows arduino genuino boards to control a variety of servo motors. Connecting the servo motor to the arduino. It makes careful use of timers.

Connect this to the arduino gnd. Working of a servo motor. The darkest or even black one is usually the ground. The servo expects one pulse every 20 ms.

On the arduino due you can control up to 60 servos.
