Arduino controlling the WTV020SD-16P Evaluation kit

WTV020SD-16P Evalation kit (3)

This article shows how you can test WTV020SD-16P module using Arduino and WTV020SD-16P evaluation DIY kit. If you have come to this page directly from a search engine, we recommend you to visit these pages to understand this project:

Connecting the WTV020SD-16P evaluation kit to Arduino:

You can see there is a 6 pin female header for connecting the kit to Arduino.

WTV020SD-16P Evalation kit (3)

  • 5V connects to 5V pin of Arduino
  • RST connects to Digital Pin 2 of Arduino
  • P04 connects to Digital Pin 3 of Arduino
  • P05 connects to Digital Pin 4 of Arduino
  • P06 connects to Digital Pin 5 of Arduino
  • GND connects to GND pin of Arduino

After connecting the kit to Arduino, load some AD4 format files on to your MicroSD card. You can Download the AD4 audio sample files. And, then stack the WTV020SD-16P module over the stackable header of the kit. Please note that the LM386 Audio amplifier module and the connected speaker are optional. The speaker connected directly to the kit is sufficient to hear the audio. But, the Audio amplifier module amplifies the sound and you can hear it more clearly.

Upload the following sketch to Arduino:

Optional Link

The output of the project:

When you upload the sketch to your Arduino, the kit starts playing music one after another. After all the songs are played, it loops back to the first one. Download the AD4 audio sample files.

wtv020sd16p.asyncPlayVoice(0);
plays song 0000.AD4
wtv020sd16p.asyncPlayVoice(1);
plays song 0001.AD4
delay(8000);
Delay sets the duration of song to be played.
wtv020sd16p.stopVoice(); 
This command stops the audio
wtv020sd16p.asyncPlayVoice(0); // plays song 0, 0000.AD4
delay(8000); // play time duration
wtv020sd16p.stopVoice();

17- The kit in action

This post shows you how to assemble the WTV020SD-16P evaluation board. You can get full description of this kit on this page.

The assembly process is straight forward. It can be easily assembled if you follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

Kit includes:

  • Bare PCB with silkscreen indicators.
  • 4 x reset tactile switch
  • 2 x 10uF electrolytic capacitors
  • 2 x 0.1uF ceramic capacitors
  • 1 x PTC resettable fuse
  • 2 x 3mm LED
  • 1 x DC barrel
  • 1 x 500 Ohm variable resistor
  • 1 x 1N4001 diode
  • 1 x 3.3V regulator chip (L78L33)
  • 1 x LM7805 (5V regulator chip)
  • 1 x TO-220 heat sink for LM7805
  • 1 x 4 pin male header
  • 1 x 6 pin female header
  • 2 x 8 pin female headers for stacking the music module
  • 1 x 470R resistor
  • 1 x 330R resistor

You need would other components that are not included along with the kit package and you need to buy those separately.

Buy these components separately:

You can get full description of this kit on this page.

Now, you can start the assembly process. We have skipped some steps on this post. If you want to see all the steps, please check this tutorial.

Step 1: Solder resistors 330R and 470R.

2- Fix 330R and 470 Ohm

See all the steps

Step 2: Solder 2 pcs 0.1uF ceramic capacitors, 3mm LEDs, 3.3V regulator and 1N4001 diode.

6- Solder 3.3V regulator

See all the steps

Step 4: Solder all the tactile switches.

7- Solder 4pcs of tactile switches

See all the steps

Step 5: Solder 2 pcs 10uF capacitors and 300mA resettable PTC fuse.

8- Solder capacitors and resettable fuse 300mA

17- The kit in action

BuildCircuit has previously published several articles about WTV020SD-16P, the best and the cheapest music module ever made for electronic enthusiasts. If you have never worked with wtv020sd-16p module, we recommend you to check out these articles. This time, we have made a very simple evaluation board for testing the wtv020sd module. It works both with and without Arduino. Click here to see the kit experiment with Arduino.

Purpose of the kit: The main purpose of this kit is to test the WTV020SD-16P music module. You just need to stack the module over the stackable header placed on the board, insert a MicroSD card and play the music stored. You can also connect it to your Arduino and make it follow the Arduino commands.

This kit contains everything you need to build your very own WTV020SD evaluation board. Simply follow the Assembly Guide and after some basic soldering, you’ll have made a fully-functional evaluation board for wtv020sd music module. The kit package does not include a wtv020sd-16p module. So, you need to buy that separately.

Features:

  • Plays music with or without Arduino. Works in mp3 mode as well as Arduino mode.
  • Supports LM386 based Audio amplifier module.
  • Works without an external audio amplifier.
  • Works with 6-9V power supply. The circuit board has 5V and 3.3V regulators.
  • It has four switches: Reset, play/pause, previous (prev) and next.
  • Includes PTC resettable fuse to protect the circuit from unexpected high current.

The kit package includes the following components:

  • Bare PCB with silkscreen indicators.
  • 4 x reset tactile switch
  • 2 x 10uF electrolytic capacitors
  • 2 x 0.1uF ceramic capacitors
  • 1 x PTC resettable fuse
