I've just bought an arduino board, and would like to try getting a stepper moving. I have a stepper from a printer. Its by FDK, now minebea, so its difficult finding the exact data sheet, but I think I've figured its unipolar from whats available. However, I have a few questions which hopefully someone will find quite simple:
1 - The arduino board takes in up to 12V. Can the microcontroller output 12V, or is it limited to 5V?
2 - the motor states it needs 24V, does this mean that I need to output 24V on each pin, or perhaps it needs a couple of pins for power and I can control it with 5V output from arduino board.
3 - There are only four pins. This says to me that there is no separate power, so hints that I do need to put 24V on each pin?
PS - if anyone wants to recommend a cheap stepper for this, would be appreciated!
