There are a few different types of motor. Each work in a slight different way and are suited to different tasks, the two types we'll be looking at today are: | There are a few different types of motor.

- | * DC - When current is supplied to the motor it will continue to turn until power is removed. Quite hard to make precise amounts of turn http:// | + | * |
- | * Stepper motors. They work by switching current to a number of separate coils in the right sequence allowing rotation in set " | + | * |
As motors need quite a bit of power they can't be powered directly from the Adruino pins. Some extra electronics are required to avoid damaging the Arduino. These are usually based around transistors, | As motors need quite a bit of power they can't be powered directly from the Adruino pins.
