Controlling Arduino using Blynk :

In previous article 3 steps to build IoT applications with Blynk mobile app   , we discussed about how to set up Blynk mobile app for developing any application.

In current article we will go through Arduino controlling using Blynk mobile app via USB.

Blynk is application which provides us dashboard as well as connectivity over the internet for IoT. The app can be download from Google play store (for Android) & app store (for apple).By using blynk app you can control led from anywhere in world over internet. Help you get to safety immediately. If you don’t know about blynk then click here to know about it.
