Using Stepper Motors
Stepper motors are great for (semi-)precise control, perfect for many robot and CNC
projects. This HAT supports up to 2 stepper motors. The python library works identically for
bi-polar and uni-polar motors
Running a stepper is a little more intricate than running a DC motor but its still very easy
Connecting Stepper Motors
For unipolar motors: to connect up the stepper, first figure out which pins connected to
which coil, and which pins are the center taps. If its a 5-wire motor then there will be 1 that
is the center tap for both coils. Theres plenty of tutorials online on how to reverse engineer
the coils pinout. (http://adafru.it/aOO) The center taps should both be connected together to
