Sensors for arduino - Microphone

[matititam]

do we already have a microphone as the simulated element?

can we use the PC/mobile microphone to emulate real microphone on wokwi?

I would like to try adding the mic to fastLED projects!

That would be a cool idea!

One challenge is that the simulation does not always run at 100%, so if we stream real-time microphone data, it might get distorted (frequency skew). But maybe it's still better than nothing?

Could also be cool to allow selecting a pre-recorded audio file or when placing the microphone, show a UI for recording a sample to store for later replay, so that the read from the microphone/sample playback could happen in sync with the simulation.

@TomasHubelbauer That is indeed a good idea..

Even if you can't run FFT, let's say due to distortion, you can get a LOT done with volume and peak detection.

There's still no user interface element, but it should capture the audio and turn the LED on when there are peaks (also plot the waveform to the Serial Plotter)
