DTMF based Load Control System

DTMF based Load Control System

In general, controlling of the home appliances can be done by normal switches. But, these days we frequently see the home automation for controlling the appliances using several technologies. This article presents the DTMF based load control system. DTMF is a signaling system for recognizing the inputs on a keypad. It is used in signaling for telecommunication over analog telephone lines in the voice frequency band among telephone handsets and communication devices. This Article discusses about DTMF based load control system.

Analog to Digital Converter (ADC) in PIC Microcontroller

April 11, 2016 by Tarun Agarwal 4 Comments

Analog to Digital Converter in PIC MicrocontrollerIn nature, there are various electrical signals like analog, which means the time varying continuous signal. In such signals, the first quantity of the signal is a voltage, whereas the next quantity of the signal can be anything like pressure, force, temperature and light accelerations. Most of the microcontrollers available in the market are digital in nature. They can only recognize high or low-level input pins. For example, if the input is greater than 2.5 volts, then it will be treated as high, and if it is less than 2.5 volts, then it will be treated as low. So, we cannot directly measure voltage from microcontrollers. [Read more…]

RFID based Attendance System Project Kit by Edgefxkits.com

Nowadays, attend system in schools and colleges is generally based on paper. So sometimes this process causes errors and also takes more time. So this project uses RFID technology to make a note of every student entering into the classroom and also to calculate the time resides in the class. In this proposed system, every student is allotted with an RFID tag. The process of attendance can be done by placing the card near the RFID reader. This article discusses about what is RFID technology and attendance system using RFID with an example project.

Know All About 22w Audio Amplifier Circuit

July 13, 2015 by Tarun Agarwal 4 Comments

Audio Amplifier

Audio Amplifier

The first audio amplifier was designed in the year 1909 by Lee De Forest when he developed the triode vacuum tube. The triode was a three terminal device with a control grid, which is used to modulate the electrons flow from the filament to the plate. This amplifier is mainly used to design the first AM radio. First audio amplifiers were based on valves which are called as vacuum tubes.But, present audio amplifiers are based on different types of transistors like FETSs, MOSFETs and BJTs. At present, there are still select valve sound and tube based amplifiers. In the year 1960, the audio amplifier which is based on transistors became hands-on with a low cost transistors in the wide range of availability. [Read more…]

How an Ultrasonic Transmitter and Receiver Work?

June 16, 2015 by Tarun Agarwal 10 Comments

Ultrasonic Transmitter and Receiver

Ultrasonic Transmitter and Receiver

Ultrasonic sound is a cyclic sound pressure with a high frequency than the upper limit of human hearing equal to 20KHz. Some animals like dolphins, mice, dogs, and bats have a high- frequency limit that is larger than that of the human ear & thus can hear ultrasound. This sound is very low in humans even at high intensities. Ultrasonic waves are found in wide industrial applications such as nondestructive testing of object is illuminated with ultrasonic waves and a repeat of the transmitted waves specifies a flaw, ball bearings, surgical instruments, Fine machine parts & several other objects can be cleaned ultrasonically.

Adder Circuit Explanation with Circuit Diagram

May 29, 2015 by Tarun Agarwal 12 Comments

Adder Circuits

In electronics, adder circuit performs addition of the binary numbers.in various computers and other types of processors. Adder circuits are not only used in ALUs, but also used in various processors to calculate increment or decrement operations, table indices, addresses, etc. A typical adder circuit generates sum and carry as the output. The main purpose of these addresses are used to add the different formats like XS-3, binary coded decimal (BCD) and gray code. When the one’s or two’s compliment are being used to specify negative numbers, it is small to alter adder to subtractor.A more complex adder is used to represent other signed numbers. The applications of adder circuit are, adder circuits are not only used to add binary numbers, but also used in digital applications such as address, table index, decoding and calculation etc. [Read more…]
