Hi again all,
I purchased a couple of these steppers http://www.ebay.com/itm/220869543972?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2648
. I fished out a ULN2003A and stuck it on my breadboard and wired it up according to the schematic in the Arduino playground and the wiring instructions from the description of the above link which state:
"Wiring Instruction : A (Blue), B (Pink), C (Yellow), D (Orange), E (Red, Mid-Point)"
I've attached my schematic below.
I uploaded the 'stepper_oneRevolution' sketch from the stepper examples in the ide, add changed the code below to 64 steps as according to the info given these have a step angle of 5.625deg. So 360/5.625 = 64 steps.
const int stepsPerRevolution = 64; // change this to fit the number of steps per revolution
// for your motor
After several attempts and searching through the forums trying a couple of different combinations for the outputs of the arduino, I am unable to get this motor to do one complete revolution in 64 steps!!
Angrily (tired at this point), I picked up my mini vice and with a well aimed (all be it accidental) shot, managed to put a rather large dent in my guitar!! LOL.
So just wondering if anyone can shed light on how to get these motors working!!
