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
BuildCircuit has previously published a project on HCSR04 ultrasonic range finder module. You can checkout the article from this link. Now, we have another article on HCSR04. It is as simple as the previous project. HCSR04 ultrasonic range finder module: The HC-SRO4 is an ultrasonic sensor which uses sonar to detect objects at a distance…
An automatic dark sensor can be made using a PNP transistor(BC557).
4 Digit Multiplexed display shield for Arduino Nano with onboard 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example, a thermometer can be made using on board LM35 sensor. 7 Seven segment multiplexed display is a tiny board and has been designed…
Bluetooth technology has become an integral part of our wireless communication landscape, enabling a wide range of devices to connect and exchange data. However, the transmission range of Bluetooth connections can vary based on several factors. Here are some key factors that affect Bluetooth transmission range: Bluetooth Version: Different Bluetooth versions offer varying ranges. The…
In this tutorial, we will use a servo and a potentiometer to make the servo motor change its position according to the given value given by the potentiometer. Components used in this project: Name Quantity Component U1 1 Arduino Uno R3 Rpot1 1 10 kΩ, Potentiometer M1 1 Servo Arduino Sketch:
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…
The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in…

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…
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:Â UM66 or BT66 is a musical IC. The following circuit generates a melody using UM66. This module can be used in a number of projects like, light operated musical bell, remote bell, infrared based music transmitter and receiver, etc.Â
TSA6014 is a compact size and powerful Bluetooth audio receiver. 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.
Description: This circuit can be used for testing your TV, DVD, VCD, etc. remote control. This is the fundamental module for making infrared based object counter. This project has been derived from “Remote tester project” .
I have taken this project from fritzing.org. This project has been released under creative commons license. This project can be useful Arduino beginners for learning 8X8 LED MATRIX. The experiment publisher has made a simple snake game. I have not tested this project, but I am sure that it should work on your breadboard also.
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…
About FTDI FT232RL breakout board:Â This tutorial is about making Arduino on breadboard using a basic FTDI FT232RL based breakout board.The pinout of this breakout board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is…
Voice Changer project can be used to transpose or distort one’s voice by encoding the sound appearing at the Microphone input. This project is built around AP8072 IC. SPECIFICATIONS Supply input : 6 VDC @ 200 mA Output : Speaker, 8 Ω / 0.5 W Audio amplifier type LM386 with volume control preset Jumper selectable…
It is just another ‘build your own Arduino’ project. BuildCircuit has worked on similar projects before. The most popular project is a DIY Arduino kit. The DIY Arduino looks similar to the real Arduino boards and uses an FTDI basic programmer to program the chips. The kit that we are going to work on this…
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…
