/*************************************************************
  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

Photon 2

C/C++

This code pulls the data from the cloud and then blinks the on-board LED in pin D7 and graphs sensor data using the Blynk application.

  // ground and are using a pulldown resistor

Photon 1

C/C++

This code takes the input from the buttons (used as sensors to see when the doors are opened or closed) and uploads it to the cloud for the other photon to download and then graph.

Schematics and circuit diagrams

We recommend using Fritzing.org for circuit diagrams. It's free and accessible to all skill levels.
