Hello,
I'd like to use my Sparkfun Digital Sandbox with the Arduino web ide, but it does not list this board among the available boards to choose from. Is it possible to use the Sparkfun Digital Sandbox with the Arduino web ide?
No, It's not possible to install 3rd party boards in the Arduino Create Editor web IDE. You will need to use the standard IDE which you can download at:
and then install the hardware package for the Sparkfun Digital Sandbox. Here's the installation instructions for SparkFun Digital Sandbox:
You could also put on the WISH LIST over in the CREATE section HERE
There is a separate section for the web editor btw.
