lol, I really don't know where I got that from... But I seem to have lost the working code for the MP3 Trigger. But anyway, the trigger.play(2); is what actually triggers the sound file...
I have tried to use different pins.
Is this:
SoftwareSerial port(12,13);
SoftwareSerial trigSerial = SoftwareSerial(2, 3);
Reassigning the SoftwareSerial if I changed the 2nd line to different pins? If it is, is there a hint to how I can make this work?
