There are plenty of LED matrix tutorials but most of them are using Arduino. Since Raspberry Pi Pico is a smaller microcontroller and it is relatively cheap, I decided to create a LED matrix with it instead.

Hardware Plan

The most common way of driving a LED matrix is using shift registers 74HC595 (datasheet).
