I'm using the Micromite and attempting to use both a "microphone" sensor to detect sounds. Nothing specific, but I'd like to trigger an LED if any sound is detected. Also I've acquired a programmable RGB strip.

Is there any code examples I could read over for either of these?

Thanks

If it is one of these sensors:



There is a digital output on the sensor. This is a threshold output that is adjustable by the potentiometer on that board. That would be usable as an input to the Micromite.

Mine doesn't have the adjustable pot.

hi eightbitswide,

interesting idea, I had this too, but did not do it, but you can see my code for the LED star .. that would be similar and also usable with a few changes or you can learn from

first i would use an ADC input channel with a potentiometer ( adjustable resistor ) to test it

You might sample the speaker signal (use an analog input), perhaps every 200mS, and look at the level of the signal over a specific threshold.

You could even use another analog input and a potentiometer to make an adjustable threshold level.

What is the RGB Strip you are using?

If they are apa 102 then have a look here
