Compiling in Arduino IDE:

1. Download all files
2. copy "arduino/lib/LiveOV7670Library" and "arduino/lib/Adafruit_GFX_Library" to Arduino "libraries" folder (If you already have "Adafruit_GFX_Library" then you don't have to copy that)
3. Rename "arduino/src" folder to "LiveOV7670"
4. Open "LiveOV7670.ino" in Arduino IDE
5. Select Tools->Board->Arduino Nano
