2019-06-29 (Sa) PillarGame

Finding a motor to drive the pillar would turn out to be a lengthy task. It started with a surplus stepper motor and a dual H-bridge driver. Not much information was available about the unit in question, but with four wires, it seemed like it would be a standard 4-wire stepper setup.
Surplus stepper motor and H-bridge

An Arduino Pro Mini was outfitted with headers and connected to the motor driver board. The rest of the evening was wasted trying to establish communication with the board. Sadly, it was lost effort, and the board is probably dead. Luckily, a replacement will be inexpensive.
No luck with this particular controller
