General
Stepper Motors
A stepper motor is an electric motor that turns a well define amount ( say 6 degrees ), a step, when connected to the right power source. Repeated activation will cause the motor to move any number of steps in either direction desired. Used for carefully controlled motion. Microcontrollers are often used as part of the drive system for a stepper motor.

Micro controller driving
Main Article: motor driver
- Arduino: "Stepper Motor Control"
- The ULN2803 is a Popular Parts for putting between a small motor and a microcontroller.
Servo Motors
A servo motor can be any kind of motor that is equipped with a position sensor. The information from that sensor is then used to control the motor. In common "RC" servos the sensor is a potentiometer and all the drive electronics are packaged inside the case with the motor.
See the motor driver page for more information on the Open Servo project.
other
- Some Microchip dsPIC controllers are designed for motor control; our DsPIC30F 5011 Development Board and ARMUS Embedded Linux Board projects include such a dsPIC.
