Assembling and Preparing the RobotsConf Sumobot with Johnny-Five
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 […]

Intel Galileo: Autonomous Navigation Rover with JavaScript
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 […]

JavaScript: A Digital Clock with Johnny-Five
The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. When I first started writing (copy and pasting) JavaScript in 1999, I focused solely on IE 5 (available on PC, Mac and UNIX; but I had no idea what it was truly capable of) and concerned […]

JavaScript: Current Detection and Measurement with Johnny-Five on Node.js
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 […]

JavaScript: LED Matrix Display with Johnny-Five on Node.js
The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. LED Matrix signs are everywhere: roadways (even cars themselves!), store awnings, offices, the grocery store deli, airports, train stations, taxi stands, libraries, alarm clocks, and so on. The use cases are so broad because the technology […]

JavaScript: ESC Programming and Brushless Motors on Intel Galileo
Previously: On-Board: Intel Galileo Programming with JavaScript and Node.js, and JavaScript: Verifying Analog Write on Intel Galileo At Bocoup, we’re commited to exploring JavaScript hardware programming; as a result of those efforts we’re excited to share a breakthrough today: This is especially exciting as it marks the first time ever that a JavaScript program was […]

JavaScript: Laser Intrusion Detection with Johnny-Five on Node.js
The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. A fairly common security mechanism, the laser intrusion detection system (or laser trip wire), is actually the composition of two devices: Laser Photoresistor, or photocell The laser emits a beam of light directly at the photocell; […]

JavaScript: Verifying Analog Write on Intel Galileo
Previously: On-Board: Intel Galileo Programming with JavaScript and Node.js When working with emerging platforms, it’s common to find yourself in a position where the platform itself requires some form of testing or validation. Often, it’s not clear how to execute these sort of validations. Thankfully, when the platform’s hardware and software is completely open, the […]

JavaScript: Relay Control with Johnny-Five on Node.js
The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. Do not attempt this tutorial with a voltage source greater than 24V A Relay is a type of actuator, or electrically controlled switch, that allows controlling one circuit with another circuit. The controller circuit is completely […]

JavaScript: Tilt Sensor with Johnny-Five on Node.js
The Johnny-Five Tutorial Series is geared towards Arduino programming on Node.js, using the Johnny-Five framework. Get caught up here. A tilt sensor is a component that senses its own change in inclination. Similar to a button, tilt sensors are activated through a physical interaction mechanism; in the tilt sensor case, this is the act of […]
