Hi! I have a 2 volt stepper and a adafruit motorshield 2.3 on a arduino uno (image is from another user, but nearly identical to mine)
I run the "stepper test" program from adafruit, and the stepper chatters: on-off-on-off. It does not complete the rotations that it should. I'm fairly certain that I am tripping some over-volt circut: if you check the FAQ, you see
How many motors can I use with this shield? You can use 2 DC hobby servos that run on 5V and up to 4 DC motors or 2 stepper motors (or 1 stepper and up to 2 DC motors) that run on 5-12VDC
Sadness. My stepper is 2 volts (specs at the bottom). Is there any way I can still safely drive this stepper?
