The New and improved RTK-000-001 / Motor Controller Board for Raspberry Pi is now pre-soldered and features a new and improved design breaking out the GPIO Pins to the side of the board.
Once you receive the board then as simple as placing it on the Raspberry Pi's GPIO header, screwing an power pack and motors into the kit and then start programming.
We officially support Python & Scratch at this point in time although you can use it with any language that allows you to control the GPIO pins including C, Java, PHP, Bash, Node.JS etc.
The chip that we use also allows the use of Software Pulse Width modulation on the Pi for example using PWM in RPi.GPIO as being able to change the value of speed in Scratch. The speed produced depends on the motors you use along with the power method used.
Best of all the new board is fully compatible with all old code!
Programming the board
As mentioned above, programming the board to drive a motor is as simple as turning a pin on or off. Example code for Python & Scratch will be available soon in the example of a robot.
