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…
This is a simple multivibrator kit using two transistors(S9014), two capacitors, and a few other components. The working principle of a multivibrator has been explained in previous posts also. You can read about the multivibrator circuit on this page. The two LEDs on the PCB flash alternately, that’s all you see on the circuit board….
The Project works as electronic toggle switch. DESCRIPTION The circuit is based on CMOSÂ CD4013Â Flip Flop IC, The circuit has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. A short button press of a tactile switch SW1 latches the circuit ON and another toggles it…
This is yet another electronic dice project from Jaycar. When you press the RED button on the PCB, all 7 LEDs flash for a while and the LEDs that stay on will represent numbers between 1 and 6. This is a basic learning kit for electronic beginners. Basic soldering skill is enough to build the…
This 16×2 LCD shield for Arduino Nano includes various add-ons, like 5 Tactile Switches, 3 Trimmer Potentiometers, LM35 Temperature sensor and the 16×2 LCD itself. It’s a compact shield designed to fit in small enclosures and it is intended to develop measuring devices like thermometers, voltmeters, timers, up down counters and other various project requiring…
Here’s a simple latch-up circuit using 555 timer and opto-coupler MCT2E. You can also use PC817 in place of MCT2E. The NE555 timer is configured in astable mode.The components are selected in such a way that the frequency output of the astable circuit lies within the audio range. Opto-coupler, MCT2E is is used for latching…
In this tutorial, will learn to use our Arduino board to display the temperature and humidity on the 16×2 LCD display using a DHT-11 sensor. For this project, you need to download the DHT11 library. You can download the library from this page. A long time ago, we had published a similar article. Please check…
This Bluetooth Music Receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.
This is a very interesting project for beginners. We had made similar project several years ago and published on BuildCircuit.COM. Check out this page. In this project, music from an audio source can be transmitted wirelessly via infrared medium. There are two kits included in this package. One is transmitter and the other is a receiver….
TSA7499 is designed for amplifier manufacturers as well as DIY users. Bluetooth/LINE IN select switch and audio input port are designed with JST connectors. So, users can install this amplifier board in a box and connect an external switch and RCA/Mono plug to make their own audio amplifier.
This is a 2x8W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. 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.
Description: This is a simple object counter circuit that counts from 0 to 9. You can make this project using four different modules listed below: Infrared remote tester RC module Counter module Astable module
Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1″ headers are mounted on the bottom of the PCB for simple insertion into a breadboard.
This do-it-yourself(DIY) sound/clap operated switch can be used for switching your 100-240V AC electrical appliances. Usually, we use a clap switch to operate a lamp and it can easily do that for you. The kit responses to clap up to distance of 10 meters, but, the further you go, the louder the clap should be.Â
A breadboard is a device for testing temporary electronics projects. Components used to test a circuit can be reused for other projects. None of the components are damaged.
Almost all people start to learn electronics using breadboard because it is the simplest way of making circuit. The photograph shows a typical small breadboard which is suitable for beginners building simple circuits with one or two ICs (chips).
In this tutorial we will learn how to change the color of an RGB LED connected to Arduino, alternating for two seconds the following colors: red, green, blue, and then orange, yellow, indigo and purple. It is similar to the previous  fade led effect experiment but it is not limited to only one LED but there…
This stepper pulse generator project is an easy solution for stepper controller drive. It’s a very important tool and can be used to drive stepper in standalone mode.  It generates square wave pulses in frequency range 0-50Khz. This project has multiple features which are a must for stepper controller. It has on board frequency generator…
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…
