Motor Controller for Arduino Powered Bigtrak Installed

Ok, so now I have the motor driver working, it is time to install it into the Bigtrak. The first job was to remove the circuit board, key pad and disconnect the wiring. With that done, I connected the motor driver to the Bigtrak's motors, 4.5v power supply and Arduino Uno.

The next job was to connect the Arduino to a separate 9v power supply, then screw the boards in place. Luckily, there are a few screw holes no longer used by the original board.

Once everything was in place I installed a variation of the blink sketch to test for functionality (code included at the bottom of this entry).
