Using Servo Motors with Arduino
The aim of this project is to learn about servo motors and how to control them using Arduino microcontroller. Servo motors are a type of actuators that are very used in electromechanics, robotics and mechatronic applications because they are responsible for the moving part of these applications such as rotating a wheel, moving a mechanical arm etc. In our case we will see first how to configure and program a servo motor to rotate forwards and backwards, then we will add to this system a potentiometer that will allow us to control the servo motor. But now I will answer some basic questions that will help us to better understand this device. How a servo motor works ? A servo motor uses pulse width modulation (pwm) to convert the signal coming to its output pin into a rotating movement. We will use the Arduino Servo library’s basic functions to apply this concept What is the difference between servo and DC motor ? Unlike a DC motor that rotates continuou...
