Thank You very much the-rebel-age for this library and example.
It works great.
And thanks chathuranga for the schematic you posted, it helped.
I have 1.5v module from the link you gave.
I use these 2gb micro SD card for all my Arduino modules that need micro SD(ethernet, tft lcd, etc.). http://www.amazon.com/gp/product/B000VOU91U/ref=oh_details_o01_s00_i00 and they work great.
Also, for others if you don't want the sounds looping put all the code you need from the void loop part of the sketch in the void setup part(leaving void loop empty or commented out), then you have full control through the module buttons.
This is all you need for setup and loop for simple playback/stop and select.
Hi the-rebel-agent,
I have the Arduino 1.0.1 Software, and when I try to verify your code the following errors appear:
WTV020.c: In function 'reset_WTV20':
WTV020.c:17: error: 'PB2' undeclared (first use in this function)
WTV020.c:17: error: (Each undeclared identifier is reported only once
WTV020.c:17: error: for each function it appears in.)
WTV020.c: In function 'send':
WTV020.c:25: error: 'PB1' undeclared (first use in this function)
WTV020.c:28: error: 'for' loop initial declaration used outside C99 mode
WTV020.c:33: error: 'PB0' undeclared (first use in this function)
I'm new to the use of Arduino, so any help will be welcomed.

Bravo, Tested library and worked fine..
And answering my previous question, I tested this with a 2GB SanDisk MicroSD card successfully. In other words there is no limitation of 1GB.
EDIT: SUCCESS, FINALLY!
I booted my computer in my windows partition and used this tool: https://www.sdcard.org/downloads/formatter_3/
to format my SD cards [Overwrite Formatting Option], I've only tried the SanDisk & Kingston but I assume the other one works too!
So the issue with the SD cards may just be [I speculate] nuances on the different implementations of available formatting tools (previously I was using gparted).
Alas, [previously] I am [was] not being so lucky.
I've tried with 3 different 2Gb microSD cards:
SanDisk, Kingston & unbranded
Formatted them all with FAT16 filesystem (and even tried to make a partition smaller than 1Gb)
Used several .ad4 files "fished" from these foruns and lately official sample ad4 files from the 4D website
Hey, thank you very much guys for your greetings. I am really pleased that my little piece of source code did something useful. I have been out of this forum but I am back. First of all, when you have a problem with this sound module, 90% of the times, blame the uSD card. IT is VERY pesky about them. Later, could be the wired, and If everything else did not work, just replace the module.
About the gap, It depends entirely on the software and the module. It seems that needs 20 [ms] to switch between tracks. That's the gap you heard. I have been trying to fix that, but seems impossible given the hardware. I also moved the pin from 3.3 to 5 in one of my modules ( I have 2 of them) and did not work. Put 2 diodes, as recommended and worked, but no so fine. Any other moved the pin and got fine results?
Hey guys, anyone using it at 5V? Cause I moved the soldered pin from 3.3 to 5 and could not get it to work. Quite erratically. I did not use any diode cause I believe they are soldered in the pcb board. Any idea?
