I wanted to find a clever way to use my old CDs that were just collecting dust because today I listen to all of my music via Spotify. I also had some NFC stickers laying around just waiting to be used for something. And like that, a new project was born. All that was missing was an understanding of the Spotify API which did not take long to learn. I wired a NFC reader (RDID-RC522) to an esp32 microcontroller and wrote some code to call the Spotify APIs to play music on an Echo Dot. The final piece was a cool case to wrap it all up. Check out my videos below for all the details.
