It is deeply wild that the “hello world” project of arduino like systems is to on-off modulate a ~500 THz electromagnetic wave emiter. (Aka blinking an led)
Also that if you want to emit in the mhz range you need permissions and specialist equipment, but in the ~500 THz range you can just use a sub-dolar part and go ham with it without needing to be a ham.
