It was also discovered that the inputs to the multiplexers had been connected in the opposite order in error, and more serious, the PIC was unable to recieve any input except from the first well. The muxes were tested on a protoboard and found to work fine. In between dismounting the circuitry from the sensor array, cutting new holes and remounting the boards, the mux boards were inspected, cleaned and repaired where necessary.   This also provided an opportunity to rethink the wiring of the sensor array so that the intereference issues discovered because of unequal grounds could be solved. This was achieved by using metal tape to restrain wires in neat paths and by keeping the grounds of the IR and yellow light detection systems separate. A diagram of the revised sensor map can be found in \ref{fig:Map}.
