This is probably how they should have been hooked up anyway to better suppress the voltage spikes caused when each coil is turned off. The voltage spikes are probably what's causing interference between the two motors.

I used this circuit and it works great. I built a second and hooked it up to two of the remaining pins on the arduino and the two motors seemed to interfere with each other and neither worked properly. Any ideas of what is needed to run multiple steppers using a few of these circuits? Thank you for posting this. I used this circuit and it works great.

When I have no load on any of the output lines to the stepper motor and check each one individualy, they work perfectly. But when I have a stepper attached (or even LEDs for test purposes, they all stay High. I would love to send the schematic of but do not see that option on this web site.

That would be of great help for me :-) a bit off topic, but how did you make the schematic picture? is there some free software to draw out your projects? That would be of great help for me :-)

I've managed to successfully control a stepper motor with the circuit in part one. The stepper motor I'm currently using is smallish like yours. I have several larger stepper motors and was wondering if it was possible to add a separate power supply and larger transistors to this circuit for the larger stepper motors. I've tried a few things, but I don't know a whole lot about electronics, so maybe you could point me in the right direction. Just a single word that I can type into a search engine could make all the difference. Many Thanks! Gabriel Great tutorial thanks!
