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…)

Build a simple DIY clap switch

Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit.

Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting amplified. And it obtains a negative square-wave which used to trigger the bistable circuit from Q2’s collector.  (more…)

How to use 315Mhz RF transmitter and receiver modules with arduino

Description: This wireless transmitter and receiver pair operate at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.

Note: These modules are indiscriminate and will receive a fair amount of noise.  Both the transmitter and receiver work at common frequencies and don’t have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link. (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();

Assembly- Breadboard power supply DIY kit

button_prev_page

This is the assembly tutorial of ‘breadboard power supply DIY kit’. You can get all the details of this kit at this link.

You will get the following components with the kit package. You can purchase this kit at buildcircuit.com.au. The web store is operated by BuildCircuit team.

Look at the PCB below.You can see the silkscreen indicators/labels of the components. If you follow the labels correctly, you can easily assemble all the components on to the circuit board.

PCB

PCB dimension: 31.75mm x 31.75mm

Step 1: Start with resistors. Solder the three resistors- 330R, 390R and 240R. Click on the resistors to get the color code.

Step 1- solder resistors 330R, 240R and 390R

Step 2: Then, fix the diode 1N4001. You can also use 1N4004 or 1N4007. All work the same way.

Step 2 Solder 1N4007 diode

Step 3: Fix 0.1uF (code-104) capacitor.

Step 3 Solder 0.1uF capacitor

Step 4: Fix the 2pcs of SPDT switch. One switch is for ON/OFF function and the other is for switching 3.3V and 5V.

Step 5 Solder another SPDT switch

Step 5: Fix the 5mm red LED. It works as a power indicator.

Step 6 Solder 5mm LED

Step 6: Fix the PTC resettable fuse (500mA). This is a handy little device that can save your system from burning. A resettable fuse (also known as a PTC) is a resistor that has very unique properties.

For this kit, if your circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would ‘trip’ (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current.

Step 7 Solder resettable fuse 500mA

Step 7: Solder the 330R resistor. It works as current limiting resistor for the 5mm LED.

Step 8 Solder the last 330R resistor

Step 8: Solder 100uF and 10uF capacitors. Please be careful with the polarity. Wrong polarity will burn the components. The silkscreen indicators should help.

Step 9 Solder 100uF and 10uF capacitors

Step 9: Solder the LM317 chip and DC barrel.

Step 10 Solder LM7805 and DC barrel

Step 10: There are 2pcs of 2-pin male header for fixing the circuit board into the breadboard holes. You need to solder them as shown on the image below.

Step 11 Solder the male headers for breadboard

Give a close look.

Step 11-Close up

Step 12: Fix the power supply into your breadboard using the male headers. Power up the circuit with any DC supply (6-37V), it will give two outputs- 3.3V and 5V(one at a time).

Step 14- 3 Powering up the breadboard power supply - Copy

The kit is ready to use for your projects. Fix your project components on the remaining part of the breadboard.

Step 13 Powering up the breadboard power supply
