Electronics Projects

We all know that Raspberry Pi is a wonderful Development platform based on ARM microprocessor. With its high computational power it can work out wonders in hands of electronics hobbyists or students. All this can be possible only if we know how to make it interact with the real world and analyse the data through some output device. There are many sensors which can…

The term digital in electronics represents the data generation, processing or storing in the form of two states. The two states can be represented as HIGH or LOW, positive or non-positive, set or reset which is ultimately binary. The high is 1 and low is 0 and hence the digital technology is expressed as series of 0’s and 1’s. An example is 011010 in which each term…

You have seen many LED torches in the market, mostly use white LEDs as they provide good brightness and light. Today we are making the low cost and highly efficient Simple LED torch light Circuit which allows your battery to live longer, for this we are using a 4049 hex inverter buffer IC. By the help of this IC, we are making a voltage multiplier circuit which doubles the…

In our previous tutorial we learnt how to install python on our windows machine and how to interface Arduino with python using a simple LED control project. If you are new, I would strongly recommend you to fall back to the previous tutorial since this tutorial is a continuation of the same.

You might have already started to wonder why we would need…

In this tutorial we are going to design an 8x8 LED Matrix Scrolling Display using ATMEGA32, which will show scrolling alphabets.

8x8 LED Matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name is LED matrix. We are going to make this Matrix by soldering 64 LEDs on to the perfboard or DOT…

In this project we are going to make a low range ammeter using ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this. Although we have few other ways to get the current parameter from a circuit, we are going to use resistive drop method, because it’s the easiest and simplest way to get current parameter.

Dice can be used to play several games, such as Snakes and Ladders, Ludo, etc. Generally, dice are made of wood or plastic, which gets distorted over time and becomes biased. A digital dice circuit is an alternative to the traditional dice; it can’t be biased or distorted, and it acts so fast that nobody would be able to cheat.

This guide will explain how to build a digital dice circuit…

Here's something interesting for the inner romantics and DIY circuit board assemblers among us. Yes, I'm talking to you, my friend; soldering iron in one hand, PCB board in the other, pining to tell your cherished special person how you feel about them, but clueless about how to express yourself. Sure, you could just tell them "I love you" — but words are nearly as…

In electronics most commonly failed component is transistor. To test the working of the transistor, one must go through a lot of testing though multimeter. By testing one terminal after another, this consumes a lot of time and also this option is no good for newbies. The transistor testing circuits which are present already are complex to understand and design. In this…

In this project we are going to design a circuit, to make a flashing light similar to that on a police car. This police light circuit is designed by 555 Timer IC and a decade counter IC. The timer here generates pulses which are fed to the 10-stage decade counter, the output of counter is so arranged to get a flashy lights as a police car.

Whenever we go to vote for elections we come to see electronic voting machines. In this project we are going to design and develop a simple voting machine by using ATmega32A microcontroller. Although we can use the controller to get more than 32 people voting machine, to keep everything simple we are going to make a voting system for a size of four people.We will…
