This web app handles the communication between the Arduino board and the Habitica server. All the action happens on "HelloController.cs". I didn't clean up all the template code that I didn't use.
We're looking for Habitica developers to try out the upcoming version 3 of the API. We are hoping that we will be ready to start testing within the next two weeks, but we're collecting testers now so that we can hit the ground running. Thanks very much for considering it, and feel free to let me know if you have any questions!
