MP3 Trigger no sound no light

Sensors Sound & Audio

Hi all

I’ve just hooked up my MP3 Trigger and I get a green light while powering up, but I get nothing, no light no sound, when I use the toggle switch.

My circuit:

24v feeding a buck converter down to 5v and an amp/speakers.

Off the 5v I have the Trigger and an Arduino Mega via a 5 fuse.

Very simple right now but I get nothing out of the Trigger when I use the rocker.

I’ve checked the file names.

Any help appreciated. :slight_smile:

How are you attempting to trigger the tracks? Maybe share a photo or video of what you’ve got so far

Also measure the 5v with a multimeter and ensure it’s actually getting 5v
