i m new of arduino and electronics. I found a stepper motor from an old self-made plotter. It has 4 wires: red, white, blue, yellow.
I want to connect it to my arduino but i m not sure on what hardware to use as interface… I follow a lot of tutorial and find L2934 (H bridge) and ULN2003A… but what is the difference?
Another thing…Watching for online tutorial and datasheet i see that the color of the wires of my stepper don’t match with any stepper i see on tutorials… so i can t recognize them and don t know how to connect it!
Thanks and sorry for my bad english :-?
