K9 Detects an Obstacle and Talks About It

This is very pre-mature but I have been working on generating events for the Raspberry PI which come from the Arduino as I have mentioned previously. Tonight was the first time I used one of these events. I have hooked up a temporary speaker and amplifier to the PI to allow it to play sounds. When the platform detects an obstacle using the Ping))) ultrasonic range finder, it stops the forward motor and sends an event to the PI. It responds by playing a sound. I thought the video was worth sharing.

The source for this interaction is available on my GitHub project but it has a long way to go.
