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 …

Start programming with Node Js and Johnny-Five: IoT and robotics based on Arduino, Raspberry Pi, Orange Pi

Johnny-Five is an open source Javascript library that allows the rapid and easy development of connected objects or small robotic projects (articulated arm, radio-controlled car …). In the previous tutorial, we saw how to replace the GPIO of the Orange Pi which fishing by its lack of libraries by an …
