Pololu VNH3SP30 Motor Driver Carrier MD01B

/*
The Pololu VNH3SP30 Motor Driver Carrier MD01B is a compact motor driver that can handle high currents and is typically used for driving DC motors. Here's a simple example of how to use the MD01B with an Arduino to control the speed and direction of a motor:

This example code sets up three pins on the Arduino to control the motor driver: motorInA and motorInB for direction control, and motorPWM for speed control. The setMotorSpeed function takes an integer value for speed (-255 to 255) and sets the appropriate pins to control the motor speed and direction. The loop function demonstrates how to use the setMotorSpeed function to cycle through different motor speeds and directions.

Note: This example assumes you have already connected the motor driver and motor to your Arduino according to the manufacturer's recommendations. Be sure to consult the Pololu VNH3SP30 Motor Driver Carrier MD01B datasheet and user guide for proper wiring and usage instructions.
