Arduino Servo Motor Controller

Connect this to the arduino gnd.

Arduino servo motor controller.

Allows arduino genuino boards to control a variety of servo motors. You can connect small servo motors directly to an arduino to control the shaft position very precisely. The library can control 12 servos using only 1 timer. 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.

The darkest or even black one is usually the ground. Following are the steps to connect a servo motor to the arduino. It makes careful use of timers. 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.

Now let s see how to use an arduino to control a servo motor. In this tutorial an arduino board will be used to power and control a small servo motor. On the arduino due you can control up to 60 servos. You can also see the 3 wires that connect to the outside world.

The guts of a servo motor is shown in the following picture. You can see the control circuitry the motor a set of gears and the case. The servo motor has a female connector with three pins. This library can control a great number of servos.

Connecting the servo motor to the arduino. 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. Connect the power cable that in all standards should be red to 5v on the arduino. The servo expects one pulse every 20 ms.

Because servo motors use feedback to determine the position of the shaft you can control that position very precisely.
