Created September 5, 2015 18:39
Simple code for detecting touch (with capactive sensing) using Arduino
#include <CapacitiveSensor.h>
/*
* CapitiveSense Library Demo Sketch
* Paul Badger 2008
* Uses a high value resistor e.g. 10M between send pin and receive pin
* Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.
* Receive pin is the sensor pin - try different amounts of foil/metal on this pin

Created August 8, 2015 03:25
This uses Johnny-Five to monitor a button and drive an LED using an Arduino
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function(){
// establish button
var button = new five.Button(2);
// establish led
var led = new five.Led(11);
