The Arduino IDE can be used with the GEMMA M0 or older versions of the GEMMA. See the Arduino Code page for this project for details. Once you have it up and running (test the 'blink' sketch), then download and install the NeoPixel library.
This step is not optional! Avoid heartbreak later by testing your circuit now.
