TSA3118 is a 2x50W audio amplifier board with AudioB plus Bluetooth module. It has perfect class-D architecture (based on TPA3116D2) and each channel has 50W power output. Both channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 10V-24V power supply. It can be used to drive any 4Ω or 8Ω…
In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph.
This is a 2x100W audio amplifier board with a new Audio B plus Bluetooth module that supports Apt-X. It has integrated ST high-performance TDA7498 chip which supports dual channel audio amplification. Both of the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-39V* power supply.
We are now selling the BLUE COLORED DIY Arduino kit This post shows you how to assemble the DIY Arduino board. 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…
The assembly of a line following robot is pretty straight forward. If you follow the silkscreen labels, you will be able to assemble it easily. The line following robot comes with the components as shown on the image. Start with resistors Solder all the resistors that comes with the package. Solder the transistors S8550 Solder…
This kit has retired, but, we have upgraded it. Please CLICK HERE FOR THE UPGRADED AMARINO SHIELD. The upgraded version of Amarino is a better kit with additional features. Fully assembled kit is also available on buildcircuit.net. About “Android- Arduino Bluetooth Communication (BTCOMM) DIY Shield- Version 1.0 and 2.0” : If you are interested in controlling…
Description: This versatile 741 operational amplifier module can be used for making a dark detector using an LDR, a photo transistor and a photo diode. The amplifier has been configured in inverting mode. It compares the change in voltage at pin 2 with the reference voltage at pin 3 and gives output at pin 6…
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…

TSIR04B is similar to TSIR04. In this device, we have removed the OLED display and put the relay board in a plastic enclosure. This is a TSIR04B Bluetooth version relay board with optically isolated inputs and temperature sensor port. You can easily control this relay board by your computer or smartphone using Bluetooth. The communication way…
In this tutorial, we will learn to make a countdown seven segment display project that counts in a sequence from number 9 to 0. To start counting, you need to press the tactile switch. At the end of counting, it flashes the LED and rings the buzzer for a few seconds.
This is a 2x8W audio amplifier board integrated with Bluetooth 4.2 . It has perfect class-D architecture (based on TPA3110D2) and every channel has 8W power output. This board can be powered by any DC 8V-16V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. The highlight point is Apt-X and TWS supported. Therefore,…
For the circuit to work as light operated musical bell, we need to connect the SW1- switch to N/C terminal of relay. LDR has to be kept in a dark case.
This project shows a combination of analog and digital circuits ready for interactive sound production! The project uses Arduino and NE555.
“Use your brainwaves to help you rest, guided by soothing music and fading lights.” – The NeuroDreamer Sleep Mask by Cornfield Electronics is a meditation device that flashes colored lights at your eyelids and plays brainwave beats for your ears to help you fall asleep, have lucid dreams, or for meditation. NeuroDreamer is open source…
