The Start\End Gate

We've started working on the start/end gate code. So far, the gate node is receiving packets and can register and display who wins. So basically, the easy part. We still need to get the cars to send special packets out when they register that they win. They sense that they win when their light sensors are in darkness. The cars need to respond to that win detection by sending out packets that start with an identifier for the gate node (we're using the number 99) and follow by their identifying number (1 or 2). The gate node then checks to see if each packet is for them, reads in the winner, and displays it. The actual gate has yet to be built. Our project for tomorrow: get the gate built and working.

Also, the new (and neat!) circuits for the car and controller are debugged and working. Now, if we want our cars to drive backwards, they're set up to do it! We just need to update our controller-to-duty period algorithm....
