Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

The picture shows how to connect the cables properly (you can ignore the second motor). There are three versions of the code: using the already implemented Stepper.h library with one motor (a second ...

The example file demonstrates how to initialize a StepperMotor object as well as all available methods with a short explanation on how to use them.

If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain ...
