In this tutorial, we will learn to use a potentiometer with Arduino. It allows us to change its value by turning a small knob, the analog value read by Arduino will enable us to do our flashing of the LED depending on the value read. Steps: -Connect the LED as shown on the image. -Connect…
The photoresistor or LDR is a resistor that varies its value according to the light falling on it and therefore it can be used with Arduino to create innovative and more complex projects. Connect the LED and LDR to Arduino as shown on the image. List of components: U1 1 Arduino Uno R3 R1 1…
This is the most basic project for Arduino beginners. Almost everyone starts Arduino with this project. The output of this project is a blinking/flashing LED. Insert an LED on your breadboard and connect it to your Arduino using wires as shown on the image. We can also use the inbuilt LED present on the Arduino…
This project shows a combination of analog and digital circuits ready for interactive sound production! The project uses Arduino and NE555.
This fully assembled sound/clap operated switch can be used for turning on your 100-240V AC light bulbs. 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 5 meters, but, the further you go, the louder the clap…
We are now selling fully assembled CLAP SWITCH(shipped from Sydney, Australia). Click here to visit the product page. If you have come to this page from a search engine, we recommend you to visit the page about DIY clap switch. In this article, we are going to describe how you can use the “do-it-yourself(DIY) clap…
Just started electronics ? And you don’t know any engineering behind your projects and you are afraid of failure ? Then, this article can help you get started in electronics. Usually, success in initial projects plays important role in electronics amateurs and engineering students’ career. Many students quit electronics because they fail in their first,…
This is a very popular digital click for beginners. It is a DIY Kit. It is now available at BuildCircuit Store. It is based on AT89C2051-24PU. Basic Functions: 1. Hour and minute display & minute and second display 2. Two alarms set up There is a buzzer that works as an alarm. When the clock reaches…
The circuit is ready for testing. Connect battery terminals and see the output. As you block light falling on LDR(Light dependent resistor), the LED glows.

THIS CIRCUIT IS EXTREMELY SENSITIVE TO DARKNESS. EXPERIMENT THE CIRCUIT IN A HIGHLY ILLUMINATED ROOM.
LED GLOWS EVEN IN LESS DARKNESS. Use torch light if the LED glows in less darkness. You can adjust the sensitivity of the circuit using a variable resistor in place of R3-300Ohm. Try this circuit with other resistances as well, for example, 1K, 10K and 100K, etc.
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…
Here’s one of the easiest, simplest and the most popular FM transmitter for amateurs and electronics beginners. With this DIY kit, you can transmit your voice or audio over an ordinary FM radio within the FM broadcast band. It is a DIY kit designed by Sagar Sapkota. You can buy this kit at BuildCircuit Store….
Assembling the infrared music transmitter and receiver kit is pretty straightforward. You can simply follow the silkscreen indicator and solder the components on its right spot.
This CSR USB-SPI programmer is the best suited kit for programming CSR series Bluetooth chips. It has much faster download speed than any other Parallel port programmer.
We are now selling BLUE colored DIY Arduino kit. Â You know that there are several versions of Arduino hardware. Hobbyists have also made Arduinos on strip boards giving different looks. Here’s one more Arduino, that is a simple do-it-yourself (DIY) kit. It is just like any other Arduino UNO board. However, it does not…
There are hundreds of electronics projects published on buildcircuit.com. This time we have selected few projects that should be easier for beginners to start with. Complex and difficult projects just frustrate the beginners. The best thing about the listed projects is that all come with good assembly images and most of the projects can be…
Remote operated musical bell can be made combining the following circuits.

When a remote is pressed, the circuit plays a music.
a) Remote tester
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
Description: The LM386 is an audio amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.
VT-100 terminal emulator is a program for communicating with any serial device using a Bluetooth serial adapter. The RFCOMM/SPP protocol emulates serial communications over Bluetooth. You need a Bluetooth serial adapter.
 In Amarino shield version 3.0, there are headers for 3 different bluetooth adapters. a. General Bluetooth Adapter – Cheapest adapter available at www.buildcircuit.net. RECOMMENDED ! b. BlueSMiRF– Bluetooth Mate Silver– More expensive adapter available on sparkfun.com. c. BlueSMiRF Gold – The most expensive adapter available on sparkfun.com. – Whichever Bluetooth adaptor you are using, the baud rate of Bluetooth adapter should match…
