Overview:

After making my Internet Controlled Ceiling Fan to send commands from my digital devices to the real world I wanted to try communicating the other way. The same Particle APIs were used to send a notification to my phones when a button was pressed on a breadboard. With the addition of a relay, this setup could easily be installed on an existing doorbell.

BOM:
-Particle Photon
-Breadboard
-Switch
