CircuitPython School - Feel the noise! Play wav and mp3 files from microcontrollers

[@film_friends]

Hey dude! Your are amazing at teaching. I bought a YX5300 on a recommendation from someone for adding a SD card and headphone jack. Do you know how to set that up to read off that card?

This is a great tutorial! It gets close to what I'm trying to figure out. I have the QT Py you mentioned! I'm trying to set it up so that while a button is pressed, a sound plays on loop and some neopixels flash. When I release the button, everything should stop. I now know I can put the neopixel code right in the audio playback code, which is great- my question is, how would I configure this to play on loop, and only while the button is being held down?

If you check out the Physical Computing Google Drive at Gallaugher.com, you'll see the challenge exercises & solutions for last week's class. Look at the code for the Fridge Alarm. While this will loop sound until a button is pressed, there's no reason why you can't test for a button press and while it's held down, continue to call the play sound. In this scenario it'll play through the file, then check the loop, so if you have a long sound file, you might see a delay after lifting your finger before the sound play stops. If that exercise solution isn't help, the definitely check out the Adafruit Discord server. Folks there are super helpful!

That’s a 3.5mm, aka 1/8” jack, not an RCA.

Yes. I stand corrected. Info for anyone looking for specifics. geekmusician.com/rca-vs-3-5mm/
