Hi,
I have installed 3 MP3 triggers (WIG-3720) at a museum, in 3 different, but near identical installations (same MP3 files).
They operate via an arduino MEGA and sounds are played via the mp3Trigger class (David Wicks).
On 2 of the installations everything works fine, on the third after a period the sound stops working, rest of the system works.
After a power down and restart of the whole system, it will work again for some time.
I have updated to the latest firmware, before installing.
I found in the forum that some early versions of the boards a small number where suffering from a similar problem.
Since the installations and museum are not easily accessible I want to make sure I can search for the error in the right way when I get there.
The mp3 triggers are connected to an amplifier.
My plan for error checking is as follows:
When the sound is not playing I will try the following to narrow down the problem:
1. See if the green led on the board is on, when activating sound via arduino.
2. Try to play sound with the onboard play button.
3. Try to attach mobile to amplifier to check amplifier output
4. Try to power OFF/ON only the MP3 trigger
5. Try to reset the arduino.
Do any of you have any comments and/or suggestions?
Best regards, Per
