Javascript and hardware: an All Girl Hack Night presentation by Kassandra Perch, February 2014

Kassandra tweaks something in one her hardware toys to make magic Javascript-controlled blinkenlights light up

At the All Girl Hack Night February meeting at ActiveProspect, Kassandra Perch gave a presentation about Javascript and hardware. She brought several gadgets that let you program hardware with Javascript: Raspberry Pi, Arduino, Espruino -- microcontroller that runs Javascript natively; and a Firefox phone, which lets you run HTML / CSS / Javascript applications natively -- as it says on Firefox phone website, "entire user interface is a web app capable of displaying and launching other Web apps". Kassandra uses this phone as a remote controller to control presentation slides written in reveal.js. Maybe she brought something else too, but I forgot. She showed us demos of code that uses johnny-five, a Javascript framework for Arduino. And the blinkenlights plugged into the Arduino actually lit up.

Javascript-controlled hardware
