A customer of mine has a Need for Speed underground machine that was using an Arduino with a robot power shield to control the steering. The Arduino got fried when the customer was trying to put it all back together after moving it and reversed the power input polarity. I have searched all over the internet and can't find the Arduino code to replace it anywhere. Does anyone on here know where I could find it or who I should contact about this?
Here's an imgur link for some photos of the machine and the Arduino with the shield attached.
