I m doing this project that needs to be ready by next Thursday. The problem I encountered was that I failed to control more than one DC Motor. I m using Arduino language to program the script. When it was only one DC Motor, it worked all right. However, I don't know how to control two DC Motors. Oh yeah, and, my DC Motor can't be going backwards for some reason....what could be the cause?? The motor was labelled as reversible.
