Category: 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.

In the previous tutorial, we discovered the Johnny-Five framework that allows to create connected objects (and more) based on Arduino, ...
