Electronics Projects

We are very much familiar with our television sets, DVDs, MP3 players, music systems and many other device that are controlled by using IR Remote. There are many types of remote controls available for different devices but most of them work on around 38KHz Frequency signal. Sometimes we face a common problem related to IR TV or other device remote control…

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while designing the board some pins are defaulted.

Now for some applications we need more than 30 pins, say if we want to…

A lot of toys have some kind of melody tones in them. But how do these tones generate? Here we have designed a simple tone generator circuit using only a single melody generator IC.  

ARDUINO UNO is an ATMEGA controller based board designed for electronic engineers and hobbyists. Arduino based program development environment is an easy way to write the program when compared to other environment development programs.

Hardware: Arduino uno board, connecting pins, 220Ω…

In this tutorial we are going to interface a 4x2 (8 key) touch keypad with ATMEGA32A microcontroller. We all know keypad is one of the most important input devices used in electronics engineering. This module does not have actual keys, but have specially designed capacitive metal pads, and these pads are very sensitive. So when a person gets in contact with one of…

In this project we are going to interface RGB (Red Green Blue) LED with Arduino Uno. A typical RGB LED is shown in below figure:

The RGB LED will have four pins as shown in figure.

The name Arduino is typically buzz word among most of the electronics students or hobbyists alike. Its ability to build things faster and cheaper with a massive online community support has made it an ideal choice for many people who are just getting started with electronics or programming. Because of its simplified hardware design and programming environment, it is possible…

Blinking LED is the first step you would like to take to get started with electronics. In this tutorial we are going to connect an LED with ATmega32, which is an AVR series microcontroller. We are going to blink the LED at half a second rate.

 Hardware:

In electronics and electrical systems, faults are very common. The most commonly appearing fault is due to discontinued connection or open circuit. To rectify such kind of faults, one could go through all the lines to identify the fault itself. Though, this method fault search is generally replaced by continuity testing equipment. There are many ways of open circuit…

All the embedded systems have memory to store data. These memory are made up of flip-flops, these flip-flops store the data in the form of bits. Each flip flop is can store one bit. So for eight flip-flops we will have 8 bit memory. This memory is used to store programs or to access the program. There are different type of flip flop here we are going o talk about SR flip-…

For an electronics hobbyist or a student 555 timer IC is one of the most important electronic components because of its functioning flexibility. One can develop different kinds of circuits using this IC. Here we are discussing a simple circuit using 555 timer IC as an ASTABLE MULTIVIBRATOR. This circuit make an LED blink for every half second, and the square wave…
