![]() Servo motors are commonly used in electronics. A servo motor contains an integrated control circuit to allow for the control of the revolution angle of the motor. There are many different sizes of motors. When using a battery, by reversing the positive and negative sides, the magnetism can be reversed and make the motor turn in the opposite direction. The internal mechanism of the motor contains enameled wire coiled many times around a magnet, and by passing an electric current through the coil the motor rotates, being repelled by the magnetism. ![]() ![]() This motor is called a DC motor, with the “DC” standing for “direct current.” Because it is DC, it can be made to move by simply attaching it to a battery. I believe that this is what people imagine when they hear the word “motor.” Many people have probably come across them while playing with radio-controlled cars. Over the next few lessons, we’ll learn about the use of motors. I assume that many products will immediately come to mind when you hear the word “motor,” but most electronic products that move or rotate use a motor.Ī motor is simply something that turns, but by using gears, we can realize complicated actions. ![]() Now things will really get going! I’d like to start working with a motor! As we have just finished our series on how to make a Stevenson screen using Arduino, you should have a good understanding of how things are working with Arduino.
