Step 5: The Code

Now let's get the board to work! Let's setup Arduino. If you don't already have the Gemma M0 board driver installed, check out this link:

Using with Arduino IDE - Adafruit Gemma M0

After you have that installed, we need to put the Gemma M0 into Bootloader Mode. To do so, press the reset button twice, and the red LED should start flashing. Make sure that your board selection is right (tools-board-Gemma M0) and so is your port (tools-port), and then upload this code:

Press the upload arrow and the light on the board should turn purple! Hit it on the side, and it should light up and play music! Now you have an awesome gift box!
