Wiring and system working fine, just can't find this code, or work out how to adapt other codes. As I know A4988 Stepper Driver can control only single motor. A logic high allows normal operation, as well as start-up (at which time the A4988 drives the motor to the Home microstep position). runSpeed() polls the motor and when a step is due executes 1 step. The time between the fastest steps you can make on a stepper motor for it to actually turn is enough for a lot of code to run in between. They also have the advantage that they are relatively cheap, Please help if you like. The key features are: This driver has 200 steps per revolution in full step (1. 584 across the vmot and ground of the driver, I have This message is an update of the project from this thread : Driving stepper motor with Arduino and L293D - Project Guidance - Arduino Forum I made quite a bit of progress on the project.
