Let there be light!

So we figured out what we want to do for our circuit -- we decided to use an 18V power source versus our old 30V source to make our circuit simpler and so that our potentiometers wouldn't have to take so much wattage. Thus, we have our source connected to 10 lines consisting of: a 100Ohm resistor, our 1kOhm potentiometer, and 10 IR LEDs in series.

And... guess what! It works!

Next step is to wire and solder the 10 lines of LEDs and place them in the rails
