This is a simple FFT 8×8 Audio LED Spectrum DIY kit. The kit package comes with all the components required to build the kit. After assembly, it works well. The assembly images very amateur and ugly soldering of the components. I should have used a reflow oven and I realized that I need to practice…
This is yet another FM receiver DIY kit for electronics beginners and hobbyists. It uses the chip CXA1619. The kit package comes with all the components required to build the kit. The schematic and description is shown below: This is the PCB of the kit. The silkscreen labels can guide you through soldering. This is…
This is yet another digital clock kit built with AT89C2051-24PU chip. We have previously made several digital clock kits for beginners and hobbyists. The kit comes with all the components required.
This is a basic electronic clock built with  STC15w408AS, clock chip DS1302, and 16×2 LCD. The best thing about this kit is its enclosure. With all the features of a commercial clock, the kit gives a professional look after assembly. The article shows you all the steps to build the electronic part of the kit…
This is a USB or computer powered amplifier with a built-in USB digital audio decoding feature. It comes with a single USB plug and there is no need of an external power supply and no external audio cable. It is a simple and convenient kit to build a basic amplifier. It uses a high-efficiency class…
CTR-30 flash Christmas tree kit consists of three circuit boards, allows 36 LED flash alternately, showing a Christmas tree in the space of a three-dimensional profile. It appears excellent at night.
This is a simple CD4060 based LED and music kit for beginners. The kit flashes the different color LEDs and plays monophonic music, that’s all. The CD4060BC is a 14-stage ripple carry binary counter. The counter is advanced one count on the negative transition of each clock pulse. The counter is reset to the zero…
This is an RGB LED contained 16×3 audio spectrum DIY kit for electronics beginners. You can simply connect this kit to any audio source and get a beautiful spectrum on the LEDs network. There is a microphone also on the kit which picks up sounds nearby.
This is yet another multivibrator kit. A similar kit article has been published recently. You can see it here.
This is a very simple NE555 based electronic kit for electronics beginners. It is a basic piano kit. I have written a similar project article before on this website. You can see it here. The kit has been built in an astable multivibrator mode. Every press of the switches results in a change in resistance in…
This is a basic electronic kit for beginners and hobbyists. It has a CD4511 chip that is a BCD to 7 segment latch decoder driver. It is a very popular chip and used widely in seven segment display projects. You can send pulses to this kit (via NE555 or any other pulse generator) and the…
This is yet again a very simple astable multivibrator circuit using NE555. The circuit produces a sound that somewhat sounds like a raindrop. This is a very basic electronic kit project for electronics beginners and hobbyists. Anyone with basic electronics and soldering skills can build this easily.
I have written several posts similar to this one before. This experiment is again about a dark sensor based on LDR or photoresistor. There are a few components and basic soldering experience should be enough to build this up. It is a good and easy kit for electronics beginners.
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….
TSA1200 has a dedicated remote control, but if the remote control is broken or you want to use your own remote control, this tutorial will teach you how to pair. Note:Â The remote control used must meet the carrier frequency of 38KHz and support the NEC standard. Hardware and Software required: audio amplifier board connection cable…
In this tutorial, we will build a circuit with Arduino Uno that can read voltages from 0 to 30V DC and display them on the 16×2 display, the ideal project to build our DIY voltmeter. Thanks to the analogue inputs, that can be used to measure voltages from 0 to 5V. For higher values ​​we…
In this project, we will build an infrared remote-controlled car so that it can be controlled with any type of infrared remote control. By modifying the design of the robot avoids obstacles we will insert an infrared receiver TSOP4838 or VS1838B or a TSOP 1738 (they only change the pin configuration) instead of the ultrasonic sensor….
How many times have we wished to have a robot that goes around the house avoiding obstacles? Creating this project with Arduino Uno, an HC-SR04 module and two wheels will take us to be a child. The robot is able to avoid obstacles, thanks to the ultrasonic range finder sensor that senses obstacle coming on…
This is yet another ultrasonic range finder project using Arduino. We have done several similar projects in the past. It allows us to control a buzzer based on the distance detected by an HC-SR04 sensor, making it sound with a frequency proportional to the distance from an obstacle.
In this tutorial, we will learn how to move a servo through the values ​​sent by a flex sensor. We can therefore take a step forward in creating robotic joints, such as moving arm hands and many other things.
