I'm using 4, TIP31C transistors to sequentially 4 coils... which should advance the disc magnet embedded in the black tube. This is a very simple concept, but I'm failing. I can only check for shorts and redo the mental wiring gymnastics so many times before I have to ask for another set of eyes. Please help!!
The LEDs are connected from Arduino outputs, through the base/emitter of the transistor. The collector and emitter are connected to the large 12V battery.
