dan-mckay / DepthImage.pde

Created April 16, 2013 21:29

A sample script in Processing from simple-openni that visualises depth map data from a Kinect

	import SimpleOpenNI.*;


	SimpleOpenNI context;

	void setup()

	context = new SimpleOpenNI(this);

	// mirror is by default enabled

dan-mckay / servocosm.js

Created April 16, 2013 10:38

This code queries the Cosm API for a reading from a remote sensor. This reading is used to manipulate a servo motor that is connected to an Arduino on the host machine. It is a Node.js application that uses the johnny-five module.

	var http = require('http'),
	five = require('johnny-five'),
	feedID = 35602, //30041, //87256
	apiKey = '1Og9wAmRBoWExjjN4LdksinNYIaSAKxVYVo0RHlHcHcvUT0g',
	value,
	oldValue,
	board,
	servo;

	// Build get request for cosm api

dan-mckay / server.js

Created April 16, 2013 09:23

This is a Node.js server script using johnny-five and socket.io that updates a web page with values taken from an Arduino with a LDR and potentiometer connected.

	var app = require('http').createServer(handler),
	io = require('socket.io').listen(app),
	fs = require('fs'),
	five = require('johnny-five'),
	board,
	photoresistor;

	app.listen(8000);

	// function for serving the static HTML page

dan-mckay / LedREPL

Created April 15, 2013 23:41

This is a simple script to demonstrate the REPL provided by johnny-five for interaction with an LED connected to an Arduino.

	var five = require("johnny-five"),
	board, led;

	board = new five.Board();

	board.on("ready", function() {

	// Create a standard `led` hardware instance
	led = new five.Led(9);

Created April 15, 2013 21:09

"Hello World" for johnny-five Node.js Module

	var five = require("johnny-five"),
	board = new five.Board();

	board.on("ready", function() {

	// Create an Led on pin 9 and strobe it on/off
	// Optionally set the speed; defaults to 100ms
	(new five.Led(9)).strobe();

	});

dan-mckay / AnalogInOutSerialThreeLED

Created November 1, 2012 14:59

Takes a potentiometer reading and controls dimness of 3 LEDs

	// These constants won't change. They're used to give names
	// to the pins used:
	const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
	const int greenOutPin = 9; // Analog output pin that the green LED is attached to
	const int yellowOutPin = 10; // Analog output pin that the ylw LED is attached to
	const int redOutPin = 11; // Analog output pin that the red LED is attached to

	int sensorValue = 0; // value read from the pot
	int outputValue = 0; // value output to the PWM (analog out)
