I am having a problem with the MP3 trigger. I have it connected like the video, but it does not want to play with EZ-B. I have connected the external power and speaker, and tested out the MP3 trigger and it works. Red Power light is on and green lights blinks like it should.
When I connect it to the EZ-B and set it up the Red power light comes on but the green light never blinks nor does it play.
I have connected the MP3 to external power and connected only the white wire to the EZ-B. The Green light goes crasy I think it is playing the different MP3 that I have on the sd card, but it is playing only a second then play the next, and the next so forth and so on. This before I even setup ARC for the MP3 Trigger.
to get the MP3 Trigger back to normal I have to remove the white wire from the EZ-B and turn off the power.
I beleive that I am runnung the most updated ARC and Firmware for EZ-B.
The wires are setup white wire to RX, Red wire to USBVVC, Black wire to Ground.
Have I missed a step? or damaged something on the MP3 Trigger?
Thanks for any help you can give me.
Thanks! The isolaters are certainly affordable-- I'll have to order one.

Is there any point to using Sparkfun MP3 trigger with the new EZ-B v4? It seems like the EZ-B now provides that function.
thanks,

Not at all Frank. I first had a MP3 Trigger installed in my B9 and pulled it out when my V4 arrived. It's a lot simpler to put sound files in a folder on your laptop and pick them with ARC then the way needed to play them from the MP3 Trigger.
Sounds like you have only two wires connected. The Mp3 Trigger needs power, gnd and signal.
As dave suggests, I would can the mp3 trigger and use the audio streaming feature of the ez-b v4.
