Hello, I am new to Arduino and electronics. Right now I am making some experiences with: 1 DC small motor (here: http://dx.com/p/mini-electric-motors-set-black-3-pcs-154836
) and a big old 9V stepper motor (4 wires: blue, white, red, yellow).
I have this driver: http://dx.com/p/l9110-dual-channel-h-bridge-motor-driver-module-for-arduino-black-157149
I think I figured out how to make the connections, but I am very scared of burning my Arduino or something. I am new to electronics, as I said, and I manifest the fear of "don't burn anything".
So can you guys please guide me to make the connections? And a part of the code?
edit: I've put a scheme for the 9V stepper made in paint. Is that good?
