And everything working at 3.3v with a new Arduino Mini Pro 8Mhz.



By the way, the laser gun was 3D printed last week:





I am about to finish this project in about 3 months.

For those wondering how this audio module works with music, here you have an example:



By the way, everything is now working with 3.3v. I just bought a new Mini Pro working at 8Mhz 3.3V, downloaded the same program I did for the previous Arduino and tada, worked out like a charm.

Why not use .stopVoice method?

Edited fist post. Hope this helps.

Will re-upload the library this night from home.

Hello!
I have a question!
How to manually change modes on vtv020-sd-16p,all ekys are on/off(loop),key 5 group of voice...
Thanks!!!
You can't. It is hardwired on those modules.

Busy pin is not always detected when using synchronous playback (playVoice), so add a delay of 50 ms before the detection of busyPin.
Add delay(50) in the line 42 of Wtv020sd16p.cpp

Good Luck!
I think that could solve the problem, but according to the manual, only 20 ms will do the job. I will test it and add that to the library, so nobody have to add code.

As a matter of fact, If you don't reset the module, internal volume won't match internal variable holding the current volume. So, If you decrement the vol without reset or initialize the module, you will suffer of weird behavior like this. I will re-check the source code and will post some recommendations.

That's the problem. reset() method set the vol to level close to 20%. That's why setVolumen(10) is not working the proper way.

No problem. If you have anything else to ask, just do it. And as I stated to @onesky, there is no quality difference working on any voltage. And won't be any difference for the library I wrote.
26  Using Arduino / Audio / Re: Arduino library for WTV020-SD-16P audio module on: December 02, 2012, 11:07:47 am
I did not notice any difference in quality working at 5v or 3.3v.

1N4007. Connected in series as you will do with two power supplies to add its volts.



5V entering to the + lead of the first diode and connecting the - lead of the second diode to the wtv.

Bellissimo! Really. Congratulations! Thanks to you I met this Arduino thing, and I am really happy about it. What's the story about that RGB led. Where did you get it and how do you use it?
29  Using Arduino / Audio / Re: Arduino library for WTV020-SD-16P audio module on: November 26, 2012, 02:34:03 pm
Here you have the wtv working at 5V with two diodes:
