pedometer.js

Playing with the iPhone's accelerometer

var win = Ti.UI.createWindow({backgroundColor:'#ccc'});
var isRunning = false;
var btn = Ti.UI.createButton({
	title:'start',
	bottom:10,
	height:50,
	left:10,
	right:10
});
var slider = Ti.UI.createSlider({
	width:240,
	max:1.0,
	min:-1.0,
	value:0
});
win.add(slider);
win.add(btn);
win.open({modal:true});

function accel(e){
	slider.value = e.x;
}

var stopPedometer = function(){
	Titanium.Accelerometer.removeEventListener('update', accel);
}
var startPedometer = function(){
	Titanium.Accelerometer.addEventListener('update', accel);
}

btn.addEventListener('click', function(){
	if( isRunning ) {
		btn.title = 'start';
		stopPedometer();
	} else {
		btn.title = 'stop';
		startPedometer();
	}
	switch(isRunning){
		case true: isRunning = false; break;
		case false: isRunning = true; break;
	}
});

Hmmm... well.... LOL
