Supposedly, you’ve already filled your theoretical knowledge gaps and prepared hardware after reading the first part. Before we move on to the essence, I just want to mention that while I was writing this part, a few questions arised that most likely would’ve stayed unanswered without Ivan‘s input – thanks (officially 🙂 ) for being so helpful!

Ok, what are we doing again?

We are going to use Temboo’s client (preinstalled on every Yún) to communicate it with API of Parse.com – a mobile backend – which will then send a push notification to Android device. As it states on the official site “Temboo makes it easy for the Arduino Yún to connect to over 100 web-based resources and services (e.g. Facebook, Dropbox, US Census data) by standardizing how you interact with their Application Programming Interfaces (APIs)”. To be more specific, it makes it easy to call these external API’s with smart code snippets called Choreos (all of Choreos are listed here).
