Hi -
I am trying to put together a simple demonstration of a stepper
motor using a BS2. The wiring diagram on the parallax site appears
to use a ULN2803 chip to do something (I might be reading this
wrong). see:
http://www.parallax.com/dl/docs/prod/motors/27964.pdf
Is this required to get the stepper motor to work? What does it do?
Is there any way to get a stepper motor to work with a BS2 and board
of education? Any help or suggestion would be appreciated.
Forever grateful,
Cary

quite a bit of current; much more so than the BASIC Stamp pins can sink
or source. You can get a stepper working on your BOE, but you'll need
to add the ULN2803 (actually the ULN2003 has enough drivers) and connect
a 12-volt supply to your BOE. For the ULN2x03 you will use Vin (12v)
instead of Vdd.
