* \ingroup pb_drv_arduino

*
* This function overrides the default (weak) implementation of the \c main()
* function in the Arduino framework. No additional setup is required to use
* this driver.
*
* \note I should really be able to use Arduino's initVariant function for
* this, but I can't seem to get it to link properly using the CMake setup in
* this repository. Overriding the main() function seems to work, and the
* USBCON thing in the default Arduino main() function isn't needed because
* puzzle modules are likely not using USB.
