// TESTING REPO COMMIT

/*
****** MAIN PROGRAM ******



Please consider that although it is an embedded envrionment we are NOT creating a HARD-TIME real time system - delays can be dealt with


Sensors are mapped on the global variable sensorsCheckSum,
which multiplies the sensor number by itself to then decode,
 which sensors are off and which are on
ie. if sensor rightright - sensorChecksum = 1*1 = 1
    if rightright and rightcentre - sensorChecksum = 1*1 + 2*2 = 5
    ...
