Arduino Servo Motor Control With Potentiometer

Servo motors have three wires.

Arduino servo motor control with potentiometer.

The example code below lets you control a servo motor with a potentiometer. I suggest you use external power to the servo. 6 1 controlling the position of the servo motor we will use an analog input to control the servo motor this will be helpfull if you decide to make something with a pan tilt platform. In this tutorial you are going to control the rotation of a servo with a potentiometer.

You can connect small servo motors directly to an arduino to control the shaft position very precisely. This can damage the arduino mg996 instant high torque. It could be applied for ex. Control the position of a rc hobby servo motor with your arduino and a potentiometer.

Sg90 mini rc servo motors can be used. Servo motor with potentiometer arduino example code. Required hardware arduino board servo motor 10k ohm potentiometer jumper wires mini breadboard. Because servo motors use feedback to determine the position of the shaft you can control that position very precisely.

Control the position of the servo motor with the arduino and the potentiometer. Power ground and signal. Analog input gets from the pot and according to this input the movement of servo change. You not connect directly the servo motor to arduino.

In contrast to the previous tutorial arduino tutorial. The power wire is typically red and should be connected to the 5v pin on the arduino or genuino board. This instructurable cane be used in combination with my 4 servos 2 joysticks instructurable to control a robotic arm. The middle pin of the potentiometer is connected to the analog pin a0 of the arduino.

The potentiometer has three pins connect the outside pins to 5 v and gnd. Servo motor control using a potentiometer knob we can use a potentiometer of any value between the 10k to 100k.
