Last minute tinkering

On the testing day we ran into a few problems. The buggy stopped working completely. We were unsure of the problem so we had to investigate. Firstly we checked that the batteries were ok (they were fine). then we attempted to reprogram the chip as this may be the cause of the problem. This is were we had the problem. everytime we attempted to re program the chip an error message appered listing a number of possible causes. This made us think that we had a wiring problem, possibly a short circuit. We then checked all connections and we even used insulation tape to prevent any close wires from touching one another. The problem was not resolved and therefore lead us to believe that our chip had gone faulty.
