Here you go
I’ve been working on this project on and off for three years. I originally started with an arduino and jumped ship when I saw the Spark Core on kickstarter.
The project involves a PN532, Photon/P1, solenoid, flow sensor, and a temperature sensor.
The app currently works on Android and Windows phone but there are a few Android phones where the NFC isn’t completely reliable…
