Dan Minear / Mbed 2 deprecated Pinewood_Derby_Timer

This is the end gate portion of a pinewood derby timer that uses an mbed. It communicates via HTTP to a web server that is doing the racer control and race management. Still need to put all that code together into a package on the net.

Dependencies:   EthernetNetIf mbed HTTPServer Servo
