- pesfandiar 7mo agoHighly recommend his Pico-based microcontroller course: https://www.youtube.com/playlist?list=PLDqMkB5cbBA4GisLzRSqw5x5G38M4zlkr https://www.youtube.com/playlist?list=PLDqMkB5cbBA4GisLzRSqw... The PWM-based modulation is interesting, but as an amateur, I couldn't fully understand it or trust that the radio receiver reliably picks up the duty cycle as amplitude.
- anfractuosity 7mo agoIf you PWM a signal, I presume you could add a filter to convert to amplitude changes?
