Designed to help you get your Raspberry Pi based Robot. This board can control DC motor as well as the stepper motor. You can connect your IR and Ultrasonic sensors to tell your robot about its environment. You can easily make your Line Following, Object following, Wall following, Maze-Solver Robots.
I refactored PiMotor to work with every stepper motor. Even with these changes the previous code will still work.
Please accept the change.
