Wifi Radio Help
Hello cherished Arduino Community!
I'm currently working on an ESP32 D1 Mini powered internet radio and i'm stuck at a dead end. I've been following this tutorial https://projecthub.arduino.cc/zetro/diy-esp32-internet-radio-4353a4. I currently don't have a Wroom laying around, so i picked the D1 Mini. It is connecting to Wifi, but the radio stations aren't loading.
I'm positive the hardware connections are fine, so it must be a code-related issue. I also added a transformer to cancel out any noise that might be caused. I think the issue lays with the links to the stations?
It's my birthday and my only wish is to make this work. pls help
