Step 6: Where to start?
Selecting which kind of motor you will need for your project will be based how you are hoping to automate your piece. If you are seeking to attach a camera to a motor to pan left to right, a servo motor will be ideal. If you are trying to drive gears forwards or backwards, you will need a stepper motor.
A really excellent intermediate control device to use, is an Arduino, or a like-style microprocessing board. The wonderful thing about these boards is that they are variable input/output devices and can be programed to complete multitude of tasks, including motor automation.
The following steps will outline how you can combine the motors we have already talked about with an interface like the Arduino.
