On the final page of the guide, you can get some hints on where to go next.

If you are just starting out with embedded electronics, give the blink example another try. Play with the on/off times of the LED and see what you can come up with.

If you feel more adventurous, try creating your own project. Navigate to your homepage where you can create a new project. Type a name in the box and click on the “Create” button.

You'll be brought to the editor page. On the left you have the control panel, and on the right is the editor.

Write your program in the editor. Then, on the control panel, select your device (Adafruit FLORA), choose the right port, and click "Run on Arduino". The program uploads to your device, and then you can test how it performs.

Have fun creating new and exciting projects.
