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

| * Dependencies: | |
| * - This code depends on the ArduinUnit library. Get it here: | |
| * https://github.com/mmurdoch/arduinounit and copy it to your | |
| * Arduino libraries folder. | |
| * - You must use a Firmata client library that has the STRING_DATA | |
| * message implemented (node-firmata, johnny-five, BreakoutJS) | |

| * Copy this into a new Arduino file, compile and upload. | |
| * It will report the available memory approximately every 10 seconds. |
