Hacking Your Maker Faire Badge
Uploading Code
With your board soldered and ready to go, you can now program your badge just like you would any other Arduino!
As mentioned previously, this board does not have an external crystal on it. For production runs of this board,the bootloader from the OpenSegment was used. Keep this in mind if you decide to overwrite the bootloader via the ICSP or ever need to reinstall the bootloader. Setting the fuse bits incorrectly for an external oscillator will lead to a bricked badge, so be very careful to double check before writing over the bootloader!
When uploading code to your board from the Arduino IDE, you will want to select the "Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328" board option. Keep in mind as you write new code for your board that you do have some pins that are not available as they are on a standard Arduino, as described previously in the #Board Overview.
