Thanks for the responses everyone! My responses inline below.
Look for a microphone module that does "envelope following" rather than a standard microphone module
IIUC “normal” microphones like this one produce a waveform of the audio which would be read in as analog. That will take some complex code to turn into what I want. Instead I should be looking for a microphone that has "envelope following" module which will be easier to use.
Is that correct? If so I’m having trouble finding "envelope following" microphones. Google keeps directing my towards stuff like this which I don’t think is what I want.
The actual current depends on how many LEDs/colors are on at the time, and to some extent how bright they are
Sorry I should have been clearer. ChatGPT says that I can add passive resistors to the “sink” (my ornament) to advertise that it can handle the full 3A. After that the actual current will be determined by the circuit with the LEDs (like you mentioned).
Take a look at my World's Simplest Lighting Effect
Nice! This will be a great starting point for me. Thanks!
I talked to chatGPT about this to see what sense the remark attributed to it might mean. It was probably referring to a time in the past where chargers "communicated" with devices by measuring resistors installed across the various signal lines.
It is drawing from this article that seems to indicate USBC can use 3A without PD negotiation. Is that no longer valid?
Here I would also just use just use a regular 5 volt 3 amp wall wart.
I thought about that but didn’t want to use one of these in a Christmas tree.
I made a few of this "lightning bolt" for a display.
Thanks! I’ll take a look.
