Attached is a diagram of what I want to try to do...
- 24V Wall Wart
- Connected to 7812 voltage regulator
- 24V fed straight into an Easy Driver board (I'm actually using a Big Easy Driver, but couldn't find a fritzing part)
- Output of the 7812 to Vin on Arduino
- GND of PSU, 7812, Easy Driver and Arduino all connected
- Additional Arduino pins for step & dir
- Easy Driver connections to bipolar stepper motor (not shown)
For simplicity sake will this approach work?
Heke -- I didn't know about DC-DC converters. If the above approach won't work I'll get one of those.
Thanks.
