@alancox We do not have a new link because as far as we know Codebender has updated its interface and it was no longer compatible with our product. If your school has made it work, could you post those instructions to this thread? I think it would be really helpful for the forum community.
Regardless of the platform (Arduino or Codebender), the lessons on Basecamp will apply to both. The only difference will be in the setup which we don't have documentation for. You will need to reference Codebender's documentation for setting up a device.
