Projekt predstavlja pametnu RGB rasvjetu koja se aktivira približavanjem magneta reed sklopki. Dok je sklopka spuštena, RGB LED diodama upravlja se putem Blynk aplikacije.

Shema prikazuje odnos između reed sklopke i RGB LED žaruljica na eksperimentalnoj pločici, kao i spojeve na odgovarajuće pinove MKR1000 Arduino pločice.

  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.

 *************************************************************

  You’ll need:
   - Blynk App (download from AppStore or Google Play)
   - Arduino MKR1000 board
   - Decide how to connect to Blynk
     (USB, Ethernet, Wi-Fi, Bluetooth, ...)

  There is a bunch of great example sketches included to show you how to get
  started. Think of them as LEGO bricks  and combine them as you wish.
  For example, take the Ethernet Shield sketch and combine it with the
  Servo example, or choose a USB sketch and add a code from SendData
  example.
