Steps

Arduino Side

  • Wire up the circuit, following the circuit diagram above.
  • Load the Arduino code to the Arduino Mega. Open the serial terminal to make sure that 15 values are being printed every 1/10th of a second.

Max MSP Side

  • Make sure that the sequencer.maxpat and saw_note.maxpat are inside the same folder.
  • Open sequencer.maxpat.
  • Change the metro interval number from 0 to something higher (I recommend somewhere between 125-250). This is the interval (in millisecond) of which the beat moves.
  • Calibrate the sensors by turning on Toggle Button # 2 and put an egg on each sensor. You should see the value goes to 0 when there is an egg, and 255 when there is not.
  • Turn Toggle Button # 1 and the speaker on, and have fun!
