Hi I have set up a circuit to control a stepper motor using an H-bridge, I followed the instructions on this website. I've seen this diagram on a couple other sites so I trust it is correct. But once I try to make the Stepper rotate it just vibrates. I have no idea what I have done wrong!
Here is the motor vibrating :https://www.youtube.com/watch?v=WoPYHDA32Zk
Here is the Tutorial I followed:http://itp.nyu.edu/~gg964/blog/archives/1369
I don't know what I've done wrong I've rearranged the wiring every which way and no matter how I arrange it the motor vibrates, if I slow it down to a snails pace the motor takes three steps forward and then on the 4th step it jumps back to where it was in step 1.
I have sent it a loop saying this:
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1
Any help would be appreciated, thanks!
