A motion-sensing light system that has 2-way communication between 2 Particle Argons and uploads data to ThingSpeak.
Automatic lights in your house may sound futuristic, but with this design it can easily be implemented in any room.
This project uses two Particle Photons, with two way communication. These photons are used to gain the attention of the other user.
