This program is designed to interface with the Spotify API to fetch song information and display it on a 64x64 pixel LED matrix using an ESP32-Trinity board. It's compatible with ESP32 microcontrollers and most LED matrix boards. A fun way to visualize your music.

To use this program, you need to set up a Spotify Developer account and create an application. This can be done with the following steps:

1. Sign in to the Spotify Developer Dashboard.
2. Create a new application (name it as you prefer).
3. Note down the "client ID" and "client secret" from your application page.

Spotify's Authentication flow requires a webserver to complete, but it's only needed once to obtain your refresh token. This refresh token can then be used in all future sketches for authentication.

Thank you to Brian Lough for all of the incredible work with ESP32 Libraries.
