Controlling MP3 trigger board

Sensors Sound & Audio
1

Hi I’m hoping someone can help.

I’m using an MP3 trigger board for a project and what I need to be able to do is play a sound when a trigger is activated and stop playing the sound when the trigger is deactivated. Essentially we have a display with 3 flaps on and when any 1 of the 3 flaps is opened the corresponding sound should play, when the flap is closed again the sound should stop.

Can this be done with this board?

Thanks,

Dan

Hi Dan.

The MP3 Trigger can’t do what you’re looking for but the WAV Trigger can if you create an INI file that changes your selected triggers to “Level Triggered.”

See the guide in the link below for details on the different trigger options.
