Alternatively, you could make two ZumoReflectanceSensorArray objects, one for the two exterior sensors and another for the two interior sensors, which might allow for cleaner code, but the drawback is that you can no longer read all four sensors in parallel with this approach.
If you later decide you want to re-enable those sensors, you can connect across the cut trace with a wire, or you can use a wire to remap the sensor to a different pin. The following example shows how you could re-enable the A2 sensor and remap the A3 sensor to pin A5 instead:

To configure the ZumoReflectanceSensorArray library to use this remapped configuration, call init with these arguments:
<syntaxhighlight lang="c">
byte pins[] = {4, A5, 11, A0, A2, 5};
reflectanceSensors.init(pins, 6);
</syntaxhighlight>
Or, if you are not using an I/O line to control the IR emitters:
<syntaxhighlight lang="c">
byte pins[] = {4, A5, 11, A0, A2, 5};
reflectanceSensors.init(pins, 6, 2000, QTR_NO_EMITTER_PIN); // 2000 = timeout after 2 ms
