A Demultiplexer is also called Demux or data distributor and its operation is quite opposite to a multiplexer because it is an inverse to the multiplexer. The multiplexer is a many-to-one circuit whereas the Demultiplexer is a one-to-many circuit. By using Demultiplexer, the transmission of data can be done through one single input to a number of output data lines. Generally, Demultiplexers are used in decoder circuits and Boolean function generators. There are different I/O configurations … [Read more...]
LED Projects for Engineering Students
In LED projects, the term LED stands for light-emitting diode, which is a semi-conducting luminous source that works on the principle of Electroluminescence. LED was invented by Nick Holonyak in the year 1962. This bulb is constructed with 2 terminals like anode (positive) and cathode (negative) where the LED glows by transmitting power from an external source. They are available in multicolor and can be controlled with a remote. LEDs provide benefits in terms of less power consumption, are … [Read more...]
What is Humidity Sensor : Working Principle & Its Classification
The humidity sensor is also known as a hygrometer, that is used to measure humidity present in the air. Generally, both the humidity sensor & temperature sensor are used to detect humidity. Humidity is defined as the amount of moisture or water content present in the air. This water is present in gaseous form in the air. A less humid air indicates that the air is dry, which generally happens for dry areas. And high humidity means a lot of water is present in the air, which is the general … [Read more...]
What is an Accelerometer : Working & Its Applications
The accelerometer is known for measuring the rate of change of speed. So, measuring acceleration has been always one of the challenging aspects in the area of electronics and instrumentation. With the advent of microelectronics and microcontrollers, measuring the rate of change of speed has found new dimensions, blended with old fundamental principles. An accelerometer is widely used to measure the rate of change of speed in three-dimensional space. These devices essentially work on … [Read more...]

They contain few Input-Output pins and limited program … [Read more...]
What is an Op Amp Integrator : Working & Its Applications
An operational amplifier is a voltage amplifier that has a differential input and a single-ended output. It is used with various external feedback components like capacitors and resistors. An operational amplifier is one such circuit that is capable of performing various calculus operations like integration and differentiation. It can be configured accordingly to perform such calculations. In the op amp integrator circuit, the output produced is nothing but the integration of the input voltage … [Read more...]
What is Damping Ratio : Formula & Its Significance
Damping of the oscillatory system is the effect of preventing or restraining or reducing its oscillations gradually with time. The damping ratio in physical systems is produced by the dissipation of stored energy in the oscillation. It is the restraining or decaying of vibratory motions like mechanical oscillations, noise, and alternating currents in electrical and electronic systems by dissipating energy. Examples of damping are; viscous drag in mechanical systems, resistance in electronic … [Read more...]
8051 Microcontroller Projects for Engineering Students
In 1981, Intel Company manufactured the first 8-bit 8051 based microcontroller and it was referred to as MCS-51 (Microcontroller System-51). The components such as ROM, RAM, timer, input/output ports, serial communication, and interrupt logic all are in-built in a controller so that the size of the overall system will be small. When we design a system with the help of a microcontroller, it will be not bulky. So, it can be used in different applications for a specific operation like electronic … [Read more...]
Solar Projects for Engineering Students
Solar projects require a power supply to operate so the power supply can be available from both renewable & nonrenewable sources. Renewable sources are air, water, and sun whereas nonrenewable sources are coal, oil, and fossil fuels. The main disadvantage of using fossil fuels is; they are very dangerous to human life while extracting, takes lots of time to produce, shortage, and have a high maintenance cost. To overcome this disadvantage, natural power resources like solar power systems … [Read more...]
