On this sample I would like to explain why PID-control should be used for speed controls and how the direction can be inverted.

Robot wirth stepper motor via microstepping, digital motion processing, auto tuning, cascaded PID controller and now with Joy Stick Control.

Play Connect Four (the common board game) against a robotic arm.

This project shows you how to successfully control a robot arm using the L9110 motor board, without using up all your Arduino outputs.
