Today is literally day 0 of learning how to solder, touching resistors, capacitors, everything. I bought an Arduino, 12V stepper motor and the Easy Driver 4.3. I needed a semi-permanent way to feed 12 volts to the steppers.
This is based on the SparkFun tutorial here
I have the 3.3v linear regulator to supply current to my LED so I'll know when the thing is turned on.
The red and black wires sticking straight up indicate which line is + and gnd out.
One thing I haven't figure out yet and hopefully someone can help me with is if my wall wart is 12v / 650 mah and each stepper is supposed to get 330 mah max will I use a resistor to downgrade the mah's? I don't understand how that works yet. Also do you suggest I place a 100uf cap on the positive out?
What do you guys think?
Thanks!!
Todd
