Introduction: How to Use WTV020SD-16P With Arduino

WTV020SD-16P is an excellent module for adding music on to electronic projects. The module can be used with/without Arduino.

There are several things to be considered while working with this module. For example, it works with only 2GB microSD card and it supports only AD4 format music file.

Check this tutorial to know about AD4 file format and other important issues of this module.

I found that the module works in two different ways:
a. MP3 mode (Without Arduino): In this mode, AD4 format music files are played by basic connection. This is the simplest mode.
The following experiment photo depicts the MP3 mode of wtv020SD-16P.

You can also check the following tutorials.
a. Mp3 mode circuit-basic.
b. Mp3 mode circuit with LM386 based audio amplifier

b. With Arduino: This music module also works with Arduino giving more flexibility in control over your music files.

What is the code? Do not be if I am using the correct one. Does it spend it to me as response, please?

You will find all the answers and code and known issues here: https://forum.arduino.cc/index.php?topic=117009.0

Can i use WTV020SD-16P for my ultrasonic sensor? Im building a blind stick.

If the left sensor senses an obstacle, it will tell GO RIGHT.

And if it detects an obstacle on the right sensor, it will tell GO LEFT.

Damn, if I saw this earlier... You should ask the "analog dude" at university ;) He worked with this before.

How did the blind stick work out? Sorry I missed the competition day was in other presentations.

Can you tell me please the differences WTV020-SD-16P vs BY8001-16P ?

If all I have is an 8GByte card ... can I reformat that to be 2GB and use that?

WTV020 chip module plug-in SD card, supports 32M ~ 1GBit capacity card

Keep the good work up my friend. Good to see that you'r active.I like this project.

I am having trouble with my WTV020-SD-16P module. I have followed the circuits given for MP3 mode but the speaker I have didnt sound. I've tried using a 1W, 8ohms speaker, a 3W, 1ohm speaker still I get the same problem. I even used an amplifier also to play the music from SD but all I hear is humming from speakers. One thing I am wondering also is everytime I put a supply of 3.3V to the module, the led connected to the busy port blinks only and sometimes it blinks first a few minutes then led turns on steady. it just turns off again when I click play and next button. What do you think is the problem?

i wanted to build a system in which there is a box and when the box is opened,the sound starts playing....sort of a jack in the box toy...plz help how to make such a connection that plays sound only when the box is opened..thanx!!
