For a future project, I pulled a stepper motor from an old 3.5″ disk drive and hooked it up to my Arduino. Turns out it’s quite easy to control these things: just periodically write bit patterns 1010, 0110, 0101, and 1001 to the 4 control wires and you’ve got a spinning motor.
I also baked six loaves of bread this weekend thanks to a cooking class on Saturday. I’m drowning in potential croutons.
