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.

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 …
