BeagleBone Black and PWM, Controlling a Servo Using HTML5, JavaScript and Node.js #beagleboneblack @TXInstruments @beagleboardorg

Babak Parvizi put together a nicely detailed 5 part tutorial on how to configure the BeagleBone Black for Pulse Width Modulation (PWM).

A lot has happened in the last couple of years, however, that has re-sparked my interest and enthusiasm. Small, faster, affordable microcomputers running embedded Linux have emerged like the BeagleBone Black (BBB). Server-side Javascript using Node.js has taken web technologies by storm, enabling devices like the BBB to seamlessly run a web server out of the box in a non-blocking I/O fashion. Open Web Standards continue to push the capabilities of HTML 5 devices, allowing mobile phones and tablets to communicate with external accessories like the BBB without the need for proprietary technologies or licenses.

In this series of posts we are going to configure the BeagleBone Black (BBB) for Pulse Width Modulation (PWM) in order to operate a micro servo. We’ll then control the servo using an HTML5/JavaScript web client that will communicate with a Node.js WebSocket server running on the BBB.
