Hug-sensing IoT Parihug toy

Here’s how to make your own telepresence hug toy. Each circuit connects to the Arduino IoT Cloud and translates your hug into a soothing vibration on the other toy. Xyla Foxlin originally developed this project as a crowdfunded product, and we collaborated to bring this DIY version to life.

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  bool hug;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.
