Hello all, I am a noob at working with these boards. I am seeking advice how to connect a normally open motion sensor to trigger a single track from the SD card on my MP3 Trigger.
Current connections:
MP3 Trigger → 3.5 headphone to RCA → Pyle 8 ohm amp with volume control → 8 ohm speaker.
Pressing the track select/rocker button plays the track no issue. I am trying to trigger the playback from a motion sensor. Is there an external board that has a NO/NC relay that can trigger the MP3 Trigger?
Is it possible to solder onto the track select/rocker button to activate when the signal is crossed?
Thanks again for entertaining what might be a remedial question.
