I’m making a Raspberry Pi Spotify streaming radio, and this week was terrible…After spending two videos making a DIY amplifier, I found that the quality was really poor, so I ended up scrapping that idea and using a premade one. I added an LCD screen to the Pi to show cover art while songs played. In theory, it was the perfect setup, but everytime the LCD screen was enabled, the audio would stop working (and it wasn’t power related). So this video is about my frustrations and trials and errors of getting this radio up and running.
