This is a sound level meter project from Jaycar. It is based on LM3915 chip. The kit displays the volume intensity via LEDs. It is a visual representation of the audio level. For the maximum volume of an audio source, the yellow and red LEDs light up. For medium sound level, only GREEN LEDs light…
This is a basic electronic DIY kit for beginners. The kit generates a light explosion effect with several LEDs. The scrolling of the LEDs is controlled by CD4017 and NE555. You can adjust the speed of the explosion using a potentiometer. You need basic soldering skill to build the kit. It takes about an hour…
This is a basic electronic kit for beginners. The kit has few SMD component and few through-hole components. Because it has SMD components, it is recommended to use a temperature-controlled soldering iron to solder the CD4060 chip. You need to set the temperature to 300°C, otherwise, you may burn the chip and the kit will…
This is a heart shaped Bicolor multiple LEDs DIY electronic kit with Happy Birthday music tune for absolute electronics beginners. This kit gives you a lot of ideas about bicolor LED, buzzer, music chip, transistors, and resistors.
This tutorial shows all the steps required to build a flashing LED rotating windmill electronic beginner soldering DIY electronic kit. The kit gives an LED swirling effect after assembly. The swirling pattern can be stopped using the two tactile switches(buttons). It is a very basic electronic beginner project for beginners. You would need basic soldering…
This is a simple blinker/flasher DIY kit with 3 LEDs, 3 transistors, 3 capacitors, and few resistors. This is a very basic and easy electronic kit for beginners. It takes about 15 minutes to build the kit. It works with a 3V-5V power supply. The video shows all the assembly steps. See all the assembly…
I recently built a DIY electronic game kit. It has 4 games: tetris, snake, plane and racing. This is the fanciest electronics DIY kit in our catalog. A do-it-yourself arcade video game! The 8 x 16 dot matrix display is of course not up-to-date, in the age of 4k UHD. But it is a lot…
It is a simple LDR based ‘Happy Birthday To You’ music player. When you block the light falling on the LDR, the kit stops playing the music. There are 18 flashing LEDs and the buzzer plays “Happy Birthday to You” song. A photoresistor or LDR works here as the photosensitive element. The jumpers are used…
This is yet another heart-shaped multicolor LED flasher DIY kit. The soldering process is pretty straight forward. The silkscreen label should guide you through soldering. It takes around half an hour to build the kit and basic soldering skill is enough to build it.
This is an LED flasher kit based on NE555 and 74HC595. The LEDs on this kit scroll and give a water flowing effect. The bistable circuit formed by NE555 and 74HC595 generates an oscillating pulse and adjusting the value of RP changes the oscillating frequency so that the flowing speed of the LEDs can be…
It’s a simple project to build a stereo preamplifier using electret microphones and the cheap operational amplifier LM358. In the past, we have made few projects comprising LM358, you can check them here. This project uses the dual-channel operational amplifier LM358. Each channel is used to increase the signal of one electret microphone and it…
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…
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.
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.
We are now selling BLUE colored DIY Arduino kit. 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.
a) Remote tester
b) Basic RC circuit
c) Simple Musical bell
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.
