#s2mini — Public Fediverse posts

so i've been holding down PIN 0 on my #ESP32 and rebooting it to put it in flash mode every time I've compiled/uploaded a sketch in #Arduino IDE and it turns out i didn't need to do that as the IDE would reboot the connected #wemos #s2mini into that mode automatically after compiling and well i've wasted a lot of time i didn't need to waste, huh.

Years ago someone gave me one of these Google DIY kits that I had zero use for at that point since I didn't have a spare #RaspberryPi and having an Alexa-type device was never my cup of tea: https://aiyprojects.withgoogle.com/voice-v1/

However, since I'm all #Esp32'ing now and looking for stuff to hook up to them, I took another look at the kit and got interested in the microphone hat. Looking around online I found someone had gotten the pinouts of the 5-wire cable, so it was just a matter of connecting it to the right parts one of my #S2 #mini boards.

The #Wemos #S2Mini has the whole I2S thing going on, so I just had to find some good code examples to see if this little board worked.

After some fiddling about, I got that little guy recording to a WAV file to its #SPIFFS file system and hosting a web server so I could download the audio.

The volume is a little low, but it's pretty cool.

However, my idea behind this isn't to record audio but to be a noise detection board that will activate at a specific threshold of sound and do something.

What it will do I have no idea. Maybe use it as an alternate method for detecting if the washing machine is still going.

I am addicted to these little boards. Help.
