IMPORTANT NOTE: The latest version of the IO Rodeo open hardware colorimeter is the Open Colorimeter. The Open Colorimeter is actively supported. We recommend you visit https://blog.iorodeo.com/open-colorimeter/ for more up-to-date information. This documentation site is for the archived Educational Colorimeter Kit. While we no longer support this version, we wanted to keep this documentation site available for anyone that is still interested in the project. If you have any questions, please email us at info@iorodeo.com.
Note: If you received a pre-programmed Arduino with your colorimeter kit you can skip this step.
Download the Arduino colorimeter firmware from here:
Unzip the downloaded repository to a known location. Inside you should see the folder called “firmware”.
Connect your Arduino board to the computer, start the Arduino IDE (installation instructions available at http://arduino.cc/en/Guide/HomePage) and open the main firmware file “firmware.ino”. This file should compile without needing to download additional libraries.
Select the Arduino Uno board model
Select the serial port it is using (under “Tools” menu of the Arduino IDE)
Upload the colorimeter firmware to the Arduino board. More detailed instructions for using the Arduino IDE can be found at http://arduino.cc/en/Guide/Environment
