JavaScript all the Things!

Arduino, Drones, Leap Motion. Combined with node.js they open the door to hardware hacking for a new generation. An overview of some of the experiments and lessons learned from a guy who a year ago could not tell the difference between a resistor and a diode.

47. Johnny Five Monday, 7 October 13
48. Code Example // JOHNNY FIVE var five = require('johnny-five'); var board = new five.Board(); // once the board is ready board.on('ready', function () { // create a new LED object on pin 13 and strobe it (new five.Led(13)).strobe(); }); Monday, 7 October 13
49. Compared to // the setup routine runs once when you press reset: void setup() { // initialize the digital pin 13 as an output. pinMode(13, OUTPUT); } // the loop routine runs over and over again forever: void loop() { // turn the LED on (HIGH is the voltage level) digitalWrite(13, HIGH); // wait for a second delay(1000); // turn the LED off by making the voltage LOW digitalWrite(13, LOW); // wait for a second delay(1000); } Monday, 7 October 13
