Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive…
WTV020SD-16P music module is one of the hot topics in current days. WTV020-SD module can be used in automotive electronics (anti-theft alarm, parking sensor, GPS navigation systems, electronic dog, central locking), smart home system, home burglar alarm, medical instruments, the human voice prompts, music player, home appliances (cooker , rice cookers, microwave ovens), entertainment devices…
The AM2302 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature. The AM2302 can connect directly to the Arduino Uno.
2 Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano. Three-pin Header Connector CN1 and CN2 provided to connect the Load. Relay has normally open…
This is a different type of digital dice. We have previously seen electronic dice with 7 LEDs. In this project, we have a seven-segment display, not LEDs. When you press the tactile switch the numbers increase from 0 to 9, and when the switch is released it stops at a random number. Using the 2…
In this article, I am going to show how to plan and make a single transistor FM transmitter on a stripboard (prototype board). This project has been tested in a 5 storey building and it works perfectly well. You can transmit your voice or audio signals from your computer or music player to a distant…
This small board is based on the CS5171 boost converter from ON Semiconductor. The board is configured to be used with a single 18650 LiPo battery. The circuit converts single-cell 3.7V LiPo battery voltage to 5V with a load current up to 400mA. Board has been designed to fit on the backside of a single-cell battery holder…
BuildCircuit has written few articles about audio amplifier and music modules. One of the most popular examples is “Audio amplifier using LM386“. This article is about a bit advanced audio amplifier made using TDA7052A. Download datasheet of TDA7052A It is not wise to connect an 8 Ohm loudspeaker directly to Arduino microcontroller pins. When we…
This is a basic up and down counter module for Arduino enthusiasts CD4029 is a presettable binary/decade up and down counter chip. Scoreduino app has a feature to control the CD4029 based up and down counter module. You can connect the CD4029 counter module to Arduino and send up and down signals via Bluetooth. It…

2 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 2 relays for switching applications in your project. The board has been designed using large current relay that can handle a load up to 30Amps. Relay circuit is optically isolated to prevent any kind of EMI noise. The board directly…
This is a 2x8W audio amplifier that has integrated Bluetooth 4.0. It has perfect class-D architecture and each channel has 8W power output. This board can be powered by any DC 9V-14V power supply. It can be used to drive any 4Ω or 8Ω passive speakers.
This post shows how to build Jaycar’s JIMINI THE CRICKET DIY KIT- PROJECT SC2 #14. It takes around half an hour to build this kit. It is basically a sound sensor. When there is a noise/sound close to the electret microphone, the circuit turns on the two LEDs and produces a chirping sound.
This is yet another sound activated LEDs circuit. I have previously published a similar project.
If you’ve ever struggled to use a solderless breadboard with an Arduino, you understand how frustrating it can be! This DC boarduino clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well…
LUX Meter project has been design to measure the illumination. Illumination is luminous flux falling on surface area of photo diode. This illumination converted to corresponding voltage using Op-Amp circuit. SPECIFICATIONS Supply 9 VDC PP3 Battery @ 20 mA  Onboard Photo Diode  Onboard preset for calibration  Range selection via jumper 10mV/LUX, 1mV/LUX, 0.1mV/LUX  Interfacing is…
This is a simple serial lcd do-it-yourself (DIY) kit based on Arduino. I derived this kit from the open source eagle file available on sparkfun.com. Â The only difference is that I used low cost components to make it more affordable. It uses the libraries and examples published on the quickstart page of sparkfun.
This project shows a combination of analog and digital circuits ready for interactive sound production! The project uses Arduino and NE555.
