Using Forth, for example it's easy to write blinky, the standard embedded "Hello World"
program.

9.2.2 Default I/O

The following pins are free for using with an Arduino Shield. You can set them up as digital
inputs or outputs and control them from Forth.

9.2.3 Reading Analog Channel 5.

FIGnition can read analog ports by simply connecting an analog input to Pin 28. Here the
reference voltage will be Vcc. The adc can measure voltages with smaller voltage steps if
you choose a different reference voltage <Vcc by connecting AVRef to a different refer-
ence voltage.
