Johnny-Five (J5)

Johnny-Five (J5) is a Javascript library that allows to develop connected objects or to do robotics very simply. An Arduino can be used, for example, to install the Firmata firmware to drive the GPIO, to control actuators (motors, servos, Led …), to retrieve measurements (temperature, accelerometry, luminosity, proximity …). Johnny-Five (J5) is available as an npm package for Nodejs or a module for Node-RED. A few lines of code are enough to start a project.

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 …

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 …
