by Tarun Agarwal 11 years ago Pulse Width Modulation (PWM) Use of PWM as a switching technique Pulse Width Modulation (PWM) is a commonly used technique for generally controlling DC power to an electrical device, made practical by modern electronic power switches. However it also finds its place...
by Tarun Agarwal 11 years ago What is an IC 4017 : Pin Configuration & Its Application Most of us are more comfortable with 1, 2, 3, 4… rather than 001, 010, 011, 100. We mean to say that we will need a decimal coded output in many cases rather than a raw binary output. We have many counter ICs available but most of them...
by Tarun Agarwal 11 years ago What is a TRIAC : Working & Its Applications We know that the unidirectional device like an SCR includes the characteristics of the reverse blocking current because it stops the flow of current in a reverse-biased state however for several applications, this kind of current control...
by Tarun Agarwal 11 years ago LED Light Sources 3 Reasons why are LEDs being used as a source of light compared to HID lamps LEDs don’t have a filament to burn out or break; therefore, they last much longer than conventional bulbs. Given that a very small semiconductor chip runs an...
by Tarun Agarwal 11 years ago Servo Motor – Working, Advantages & Disadvantages Servo implies an error sensing feedback control which is utilized to correct the performance of a system. It also requires a generally sophisticated controller, often a dedicated module designed particularly for use with servomotors. Servo...
by Tarun Agarwal 11 years ago RFID Tags & Applications What is an RFID tag? The RFID tag is a microchip with an antenna in a compact package. The Tag can be attached to the object to be tracked through Radiofrequency. The Tag’s antenna picks up the signals from the RFID reader and then returns...
by Tarun Agarwal 11 years ago Temperature Controller Temperature is the most often measured environmental quantity and many biological, chemical, physical, mechanical and electronic systems are affected by temperature. Some processes work well only within a narrow range of temperatures. So...
by Tarun Agarwal 11 years ago Temperature Sensors – Types, Working & Operation Temperature is the most often-measured environmental quantity. This might be expected since most physical, electronic, chemical, mechanical, and biological systems are affected by temperature. Certain chemical reactions, biological processes,...
