    Help with a stepper motor IC

    Yes, also the faster I send the high then low signals the faster it vibrates

    Help with a stepper motor IC

    The CWB pin is just a direction pin, and the MODE is for half stepping compared to full stepping. I do not think that they need to be set. But just in case, I tried every combination of on/off when running my code, and it didn't change anything. So, yes I had them connected, and I am pretty...

    Help with a stepper motor IC

    I used a voltmeter to check which of the remaining 4 wires (besides the center taps) were connected. So I know which wires are A, A centertap, AB, B, B centertap, and BB. So I know I have them connected to the IC correctly. I guess I am just wondering if the code is right for how the chip looks...

    Help with a stepper motor IC

    I know which 2 wires are the center taps, of the 6, and the way I had it set up, is the arduino's ground and the 12v ground I had connected to the same rail on a bread board, then the 12v (24v in the datasheet) connected to the center taps. when you say +ve supply rail, do you mean the 12v I...

    Help with a stepper motor IC

    Well, I have the STK672 chips, which are stepper motor driver IC's. unless there is something I missed, on the datasheet for those chips, the arduino only needs to send the clock signal to IC and then the IC takes care of sending the correct 5-24v (depending on the stepper) to the correct pins...

    Help with a stepper motor IC

    I took apart a couple office printers and got several stepper motors, which is great for electronics projects. the problem I am having is with driving them. Also from the same printer I got each of the IC's that ran each of the stepper motors, in my haste to get the parts, I took them off the...
