  // map sensorReading to an output between 100 and 1000, set frequency to this
  // sound is my mapped variable that stores the frequency value to send to my speaker
  sound = map(photoValue, 80, 919, 100, 1000); // 80 and 919 were the average high and lows of the photosensors

  // change the pitch, play for 10ms - use tone()
  tone(8, sound); // parameters are the pin, and frequency
