can audio fx board be used as output on pins?

Post by codejoy »

I saw this:
https://learn.adafruit.com/adafruit-aud ... -board/faq

can the audio fx soundboard have their pins set to output or a few of them? so I could trigger a sound on pin 1 and then make a LED lightup on pin 2 say? or even run a 5v selenoid? like this one on pin3:

(Guessing a diode in there somewhere too.)

Just wasn't sure if it could do outputs to pins.
Lastly sounds like the firmware is built to trigger based on wav file name, can I still trigger a wavefile but just do it via code? (guessing thats the serial audio control?)

Those are GPIO pins, but the firmware on the board uses them as inputs.

Yes, if you want full control over that is played, the serial interface will let you do that. You would need to drive it with an MCU board, though.
