Building an ultrasonic sensor backpack

Note: This is a bit of a scratch to see what's involved in getting the ping sensor to work as an I2C backpack.

Dependencies.

I did this on a Trinket as that's what I had to hand to make programming a bit faster. If you use a trinket you will need the custom arduino. Check out the Adafruit Trinket info https://learn.adafruit.com/introducing-trinket/introduction

You also need a custom form of the TinyWireS library that manages sending multiple registers on one read request (the

	return function () {
	var args = Array.prototype.slice.call(arguments);
	return self.apply(bind \|\| null, args);
	};
