Labeled LCD Display and I2S Converter
I had to research the pinout of the LCD Display and the SD Card. I also learned how an I2S Converter works and what pins they need to be connected to on the Pico.
I Also added an LED Indicator for when the board is being powered.

Wired the Keys and Rotary Encoders
Following the tutorial, I used matrix wiring to wire all the keys and rotary encoders.
It took me a stupid amount of time to realize that the reason the keys were in the order of a piano keyboard.
I also put labels on all the GPIO pins on the RPI Pico symbol.
