Raspberry Pi Pico Audio output
In this video I create a very basic and simple PWM based audio output circuit and take you through the code on how to output recorded WAV files.
This is not intended to be the highest quality audio circuit. The main idea is to keep it simple.

00:31 Circuit Diagram
00:56 Building on a Breadboard
01:18 Pico Code Explanation
04:30 Code to covert WAV files to C arrays
05:44 Demo of Audio Working!
The circuit is derived from the 'Hardware Design Guide with RP2040' (which is the RPi Pico) https://datasheets.raspberrypi.org/rp...
