This experiment demonstrates how the Arduino can be used to connect and run a servo motor. Servo motors are useful for metering/dispensing, winding and walking (in robotics). They can also be found in many radio controlled appliances such as solar panels which can track the movement of the sun to gain more energy as opposed to remaining stationary.

Typically, a servo motor can be positioned from 0 to 180 degrees. Its position is controlled through timed pulses, meaning that increasing the time will increase the angle as well and vice versa. If the pulse is sent within a certain amount (usually 25-50 milliseconds) the servo motor will function smoothly as can be seen in this video.

The next step would be to modify the servo so that instead of only 180 degrees, the motor would spin all the way around.

Although this is a simple experiment demonstrating one of the uses of an Arduino, the possibilities for micro controllers in all fields of research exist.
