"StepperMotor" by Wapcaplet; Teravolt. (http://adafru.it/enC)

There are four essential types of steps you can use with your Motor HAT. All four kinds will

work with any unipolar or bipolar stepper motor

1. Single Steps - this is the simplest type of stepping, and uses the least power. It uses

a single coil to 'hold' the motor in place, as seen in the animated GIF above

2. Double Steps - this is also fairly simple, except instead of a single coil, it has two coils

on at once. For example, instead of just coil #1 on, you would have coil #1 and #2 on

at once. This uses more power (approx 2x) but is stronger than single stepping (by

maybe 25%)

3. Interleaved Steps - this is a mix of Single and Double stepping, where we use single

steps interleaved with double. It has a little more strength than single stepping, and

about 50% more power. What's nice about this style is that it makes your motor

appear to have 2x as many steps, for a smoother transition between steps

4. Microstepping - this is where we use a mix of single stepping with PWM to slowly

transition between steps. It's slower than single stepping but has much higher

precision. We recommend 8 microstepping which multiplies the # of steps your

stepper motor has by 8.
