// QTR-8RC module.  These reflectance sensors should be connected to digital inputs 3 to 10.
// The QTR-8RC's emitter control pin (LEDON) can optionally be connected to digital pin 2,
// or you can leave it disconnected and change the EMITTER_PIN #define below from 2 to
// QTR_NO_EMITTER_PIN.

// You can test this by taping a piece of 3/4" black electrical tape to a piece of white
// paper and sliding the sensor across it.  It prints the sensor values to the serial
// monitor as numbers from 0 (maximum reflectance) to 2500 (minimum reflectance).
