Create Android App Using MIT App Inventor With Blynk API

How to use Blynk without Blynk app?

Introduction

Blynk app is very popular among students in IoT (Internet of Things) project development. However, since it is very easy to use, it makes your project looks simple. Yes, you can create your own app, server, API, but it will take time, and require a lot of resources too. So we try to make it not too easy and not too hard. We create our own app using MIT App Inventor with Blynk API. It means, you create app, but still using Blynk server and API.

This tutorial require basic knowledge for:

  • Raspberry Pi – Know how to start, connect to the internet and access your Pi.
  • Blynk – Register to get Blynk Authentication Token, familiar with the layout and know about Blynk virtual pin.
  • MIT App Inventor – Register, familiar with the layout and know how to connect to your Android phone.
