These LEDs can be accessed as an array, using a specific library. See the mapping below:

LED matrix number mapping.

This matrix can be used for a number of projects and prototyping purposes, and supports animation, simple game

designs and scrolling text among other things.

9 Digital Analog Converter (DAC)

The UNO R4 WiFi has a DAC with up to 12-bit resolution attached to the A0 analog pin. A DAC is used to convert a

digital signal to an analog signal.

The DAC can be used for signal generation for e.g. audio applications, like generating and altering sawtooth waves.
