Arduino Noteboard

This instructable will be showing how to create a Arduino Noteboard. This board is able to play a whole A-A octave and their flats.

Materials:

18 male-male wires

16 buttons

18 mini jumper wires

4 male pins

4 Alligator Wires

2 Speakers

2 Bread Boards

2 Arduino Boards

2 Power Supply Cords

Step 1: Wire Your Breadboard

Equally space out your buttons across the board. Connect a male-male wire a few spaces above the button to a pin. Going left to right, assign your buttons to pins 2-9. Use the jumper wires to connect your button to the power supply line. Use a jumper wire halfway through the power supply board, between 25 and 30, to connect the power. Use a male-male wire to connect the corner power supply line to the GND pin.

Repeat this step for your second board.

Step 2: Wiring Your Arduino

Your pins 2-9 should be connected to your respective buttons, left to right. Your GND pin should be connected to the breadboard power supply as well. Place male pins on the second GND pin and on the 11 pin. You will be attaching alligator wires to this.

Step 3: Speakers

Take your alligator wires and clip it to the speaker. Clip the 11 pin alligator wire to the positive and the GND alligator wire to the negative.

Step 4: Review Wiring

The wiring should be complete. Check wires for complete connections and proper placement. Go back through these steps if you are unsure on any wires.

Step 5: Coding for Natural Note Board

This code defines a letter as a note frequency. Then it assigns each pin a note. Then it supplies power to each pin.

This code was inspired by The Lonely Programmer.

Step 6: Coding for Flat Note Board

This is the same as the last step, but the frequencies have been changed. This code defines a letter as a note frequency. Then it assigns each pin a note. Then it supplies power to each pin.

This code was inspired by The Lonely Programmer.
