Introduction Platform IoT Blynk & ESP8266

This time the test will be performed on the well-known Blynk platform.

What is Blynk? A platform differences seen earlier blynk is a solution for building IoT applications available for Android and iOS. Based on platforms known as Arduino, Raspberry pi, ESP8266, Intel Galileo, Particle, Serial devices and Wifi among others, in a few minutes you can create a high quality dashboard, we highlight the large number of available widgets, Control, display, Notification and Video Steaming.

In this case we will perform the Tests with Module ESP8266 in the following tuturial show step by step installations and configurations for the Blynk application.

Our test will do 2 things:

Visualization of the value of ADC0 (LDR)
GPIO04 control (Led diode)

This widget will read the ADC0, given the signal conditioning of the light sensor (LDR) we set the ADC from 0 to 200 points, with update of 2 seconds of sampling.
