The code does not compile properly


First, make sure you have an Arduino IDE version 1.6.12 or higher. If not, you can download it from the Arduino website.

Compiling issues usually indicates a problem with the download or upload of the code (for example copy -paste of the code) or problems with saving as ZIP files.
The proper way to download the code is:

  • Download the code
  • Unzip it
  • Double click (don’t drag and drop) firmware.ino - all the files in the folder should open in the Arduino development environment. (They’re all libraries you’ll need to run the code).
  • Upload to Arduino and Go! Remember- The code provided is a sample for you to get started.
