Servo motors are great devices that can turn to a specified position. Usually, they have a servo arm that can turn 180 degrees. Using the Arduino, we can tell a servo to go to a specified position and it will go there. As simple as that!
Servo motors were first used in the Remote Control (RC) world, usually to control the steering of RC cars or the flaps on a RC plane. With time, they found their uses in robotics, automation, and of course, the Arduino world.
Here we will see how to connect a servo motor26 and then how to turn it to different positions.
The first motor I ever connected to an Arduino, seven years ago, was a Servo motor. Nostalgic moment over, back to work!
For this recipe, you will need the following ingredients:
An Arduino board connected to a computer via USB
A servo motor
Jumper wires
There are few big names in the servo motor world. Hiteh and Futaba are the leading RC servo manufacturers. Good places to buy them are Servocity, Sparkfun, and Hobbyking...
