MicroSD card breakout board for Arduino

This is yet another MicroSD card breakout board for Arduino. Previously, we had released a similar MicroSD breakout board on our website. This module is bit cheaper than the previous one, that’s the only difference.

As we all know most of the microcontrollers have  limited built-in storage. For example, Arduino UNO (Atmega328) has 1Kbytes of EEPROM storage and it might not be enough for all projects. If your project has any graphics, video, audio and data logging feature, you need a removal storage in it.

If you are working with some sort of data logging, graphics or audio, you will need at least a Megabyte of storage. In order to get that kind of storage, you need flash cards, or SD or microSD cards. These days, most of the micrSD cards come with minimum 2 gigabytes space in it. You can store data logging files on to your SD card and access the files using inbuilt SD card reader on your computer or using an external reader.

How to use Micro USB 5V 1A Lithium Battery Charging Board/ Charger Module

Lithium battery charger (2)

Here is a simple and a low cost Lithium Battery charging breakout board. This article is about the charger breakout board based on TP4056.

It uses a Micro USB for connecting the breakout board to any computer or ‘USB wall adapter’. It works with linear charging method. It offers 1000mA charge current by default but it is adjustable from 50mA to 1000mA by soldering a resistor. The default resistor soldered in on the board is 1.2K Ohm. A resistance and current table has been shown below on this page. (more…)

Experiment with DHT11 and Arduino

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. (more…)

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.

SAMPLES FILES 2

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();

WTV020SD-16P evaluation board- DIY kit

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
  • 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 things that are not included along with the kit package and you need to buy those separately.

USBtinyISP V2 AVR ISP Programmer

Officially supported by Arduino IDE, it can burn Arduino bootloader onto chips, and practically program any Atmel AVR microcontroller by this powerful AVR ISP programmer.

Summary

  • Assembled and ready to use
  • 6-pin AVR-standard interfaces
  • 2 LEDs to indicate “USB/Power good” and “Busy”
  • USB powered
  • USB cable (A to B type) is NOT included

How to use USBtinyISP V2 AVR ISP Programmer ?

  1. Download driver, unzip and install
  2. When you see “USBtinyISP AVR Programmer” in device Manager, the USBtinyISP is ready to use.
  3. There’s a jumper sticking out near the USB cable, PWR . When the jumper is in place (connecting the two wires), that means that the USBtinyISP is providing 5V power to the device being programmed. If you don’t want to power the device then just take the jumper out. We will need the jumper in place when burning bootloader for Arduino
  4. Connect USBtinyISP and ICSP of Arduino with the 6-pin cable included. Then connect USBtinyISP to the computer by USB cable (A to B type), this cable is not included
  5. After the hardwares are connected, we can start the Arduino IDE. Under the list of “Tools”->“Board” , choose your Arduino version. Then click “Tools” -> “Burn Bootloader” -> “w/ USBtinyISP” to start burning Arduino bootloader
  6. During burning, you will see the “BUSY” Led flashing
  7. It will take a while to burn (but still faster than USBasp ). You will see “Done burning bootloader” at Arduino IDE when it is done.
