Blynk IoT Platform

Blynk was designed for the Internet of Things. It is most popular IoT Platform. It can control hardware remotely, it can display sensor data, it can store data, vizualize it and do many other cool things. With Blynk Library you can connect over 400 hardware models (including ESP8266, ESP32, NodeMCU, all Arduinos, Raspberry Pi, Particle, Texas Instruments, etc.)to the Blynk Cloud. Full list of supported hardware can be found here.

There are three major components in the platform:

  • Blynk App – allows to you create amazing interfaces for your projects using various widgets we provide.
  • Blynk Server – responsible for all the communications between the smartphone and hardware. You can use our BlynkCloud or run your private Blynk server locally. It’s open-source, could easily handle thousands of devices and can even be launched on a Raspberry Pi.
  • Blynk Libraries – for all the popular hardware platforms – enable communication with the server and process all the incoming and outcoming commands.

Now imagine: every time you press a Button in the Blynk app, the message travels to space the BlynkCloud, where it magically finds its way to your hardware. It works the same in the opposite direction and everything happens in a blynk of an eye.

What do I need ?

1. Hardware.

An Arduino, Raspberry Pi, or a similar development kit.

Blynk works over the Internet. This means that the hardware you choose should be able to connect to the internet. Some of the boards, like Arduino Uno will need an Ethernet or Wi-Fi Shield to communicate, others are already Internet-enabled: like the ESP8266, Raspberry Pi with WiFi dongle, Particle Photon or SparkFun Blynk Board. But even if you don’t have a shield, you can connect it over USB to your laptop or desktop (it’s a bit more complicated for newbies, but we got you covered). What’s cool, is that the list of hardware that works with Blynk is huge and will keep on growing.

2. A Smartphone.

The Blynk App is a well designed interface builder. It works on both iOS and Android, so no holywars here, ok?
