Getting Started With Blynk On The Raspberry Pi 3+
Blynk is a powerful Internet of Things (IoT) app for iOS and Android that allows you to control your Arduino, Raspberry Pi, or ESP8266 from your mobile phone. On your phone, the Blynk app allows you to build your own control interface without any complicated coding. It also runs on the target device (in our case, the Raspberry Pi) and handles all of the communication between the two over the internet. Building a complex IoT device has never been so easy!
In this tutorial we are going to look at the basics of setting up Blynk for the Raspberry Pi. Unlike the Arduino platform, setting it up on the Raspberry Pi is a little more involved so we have made this handy tutorial to get you up and running in no time. There are a lot of different operating systems out there for the Raspberry Pi, so we are going to focus on the most popular: Raspbian. We are using the version dated: November 13, 2018. Deviating from this version may result in different / additional.
