Looking for some creative inspiration for your next hardware programming project? Come meet Rick Waldron, Francis Gulotta, and five of their newest robot friends this weekend at the Bay Area Maker Faire, May 20-22! Reconbots are WiFi car devices you drive from your phone using their live video stream and touchscreen controls. They are powered […]

After three years of community development, Johnny-Five has its own home on the web – we’re thrilled to announce johnny-five.io! The new site combines content from the repo, the wiki, tutorials from the Bocoup blog and several third-party websites into a single, easily-discoverable source: If you want to find the API documentation, that’s right here. […]

On March 5, 2015, Technical Machine announced the next generation of their Tessel platform: the Tessel 2. Additionally, Technical Machine announced a prototype-to-production service for products that are built with the Tessel 2. These are both very exciting developments for the future of NodeBots. According to Technical Machine, the Tessel 2 builds on and grows […]

In the first post in this series, I walked through inventory, preparation, calibration and assembly of the SumoBot Kit that was provided to all attendees of this year’s RobotsConf. From there, I showed how to control the bot with an Arduino Uno, Electric Imp and Spark Core. In this article, I’m going walk through two […]

In this article, I’m going introduce a simple program to for controlling the assembled SumoBot with an Arduino Uno. This entire article will assume that the you have already […]

At this year’s RobotsConf, the theme of the event was “Everyone Builds a Robot”. Creator and curator Chris Williams facilitated this by including a SumoBot Kit (designed and produced by Paweł Szymczykowski) and an ARDX Starter Kit for Arduino in the “swag bag” that every attendee received at registration. The bag also included an Arduino […]

Earlier this year, I published an article that announced support for running Johnny-Five programs directly from an Intel Galileo Generation 2 single board computer. Since then, a lot of work has gone into fine tuning Galileo-IO, including a complete internal redesign that takes advantage of native I/O bindings and processing capability improvements whenever possible. Over […]

The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. In certain cases, it may be useful to know how much current is drawn from a specific load in a circuit. In this article, we’ll measure current draw, with and without a load. The load will […]
