After a successful trial controlling LEDs on an Arduino from my Raspberry Pi, the next logical step was to try sending music. My goal is to use the Raspberry Pi as a central “brain” that stores audio files and streams them to multiple Arduinos. Each Arduino then acts as a signal converter for an old telephone handset. However, I quickly learned that “playing music” is fundamentally different from “switching a pin.”
I also managed to write my Python code in VSCode via SSH on my Raspberry Pi.
