Blynk

Blynk is an open source project that makes available a private local server (which is not limited in scope). Blynk is an application for iOS and Android which allows to quickly develop connected objects based on Arduino, ESP8266, Raspberry PI. Energy) as well as many libraries in different languages (C ++ for Arduino, javascript, Node-RED plugin …)

Connecting an ESP8266 to Blynk on WiFi with Johnny-Five (Firmata WiFi)

In the previous tutorial, we discovered the Johnny-Five framework that allows to create connected objects (and more) based on Arduino, Raspberry Pi (or Orange Pi) in Javascript. Johnny-Five is also a very good solution to replace the GPIO of an Orange Pi by an Arduino Nano v3. In the previous …

IoT development based on Orange Pi, Arduino (Firmata), Nodejs, Blynk and Johnny-Five

In this tutorial, I propose to combine Nodejs/Johnny-Five with Blynk to remotely control the GPIO of the Arduino/Firmata from a smartphone or a tablet and to make measurements (temperature and atmospheric pressure of a BMP180 in I2C ). In the previous article, we saw that it was very easy to …
