Download the Arduino Library

IMPORTANT: You need to download an older version of the Arduino IDE in order to compile/upload the LedCube Library to your Arduino board. Go to this page and download version 1.05 of the Arduino IDE for your operating system https://www.arduino.cc/en/Main/OldSoftwareReleases#previous.

Then follow these instructions:

  1. Click here to Download the library
  2. Unzip it to the Arduino libraries folder

If everything is correct you should find an example in the Arduino software under File > Examples > LedCube > ledcube.
