Starting with the Arduino on Windows

1. Plug a USB cable into your PC and the Arduino
2. Download the Arduino software and extract it
3. Run Arduino.exe
4. Paste in a program like the following, which writes a constant value to pin 9
   foo
5. Go to Tools>Board and choose your board
6. Go to Tools>Serial Port and choose a serial port
7. Press the upload button from the toolbar-- it looks like an arrow pointing to the right
8. If the upload fails, keep trying serial ports until it does work
