Wav Trigger

Just purchased one plugged it in but having problems.

When I plug in a 9v power supply and I have a 64gb micro sd sandisk ultra inserted, the led flashes approximately 6 to 8 times very fast. no sound through headphones. It then flashes about every 3 secs. When I press the button nothing happens.

The sound files are from either robertsonics or sparkfun.

I have tried using this format 0001_Number.wav

and the standard one 001_Number.wav

but no difference.

I have tried copying files using mac and pc with no difference just a rapid set of flashes then a slow pulse.

Any ideas on how to get it working. I have plugged the same headphone and lead into a adafruit audio fx sound board and headphones work.

Hi Gene.

The WAV Trigger supports up to a 32GB SD card, try a smaller SD card and make sure it’s formatted FAT32 and you should be OK.

Thanks

It now works , I never seen that there is a size limitation sigh

cheers.
