LED Flasher Circuit Project Overview : This project involves the design‚ documenting and building of a LED flasher circuit controlled by a software program written in the C programming language. The hardware circuit consists of a PIC 16F684 microcontroller‚ ten LEDs with resistors ‚ and two switches. Software Program The software program will read the settings of the two switches. If both switches are off‚ the LEDs are all off. Any other switch settings will start the LEDs flashing in a unique pattern

generation computer. Second generation (1959-1965) computer consisted of transistors i.e. vacuum tubes were replaced by transistors. Thus the size of the computer got reduced considerably. Third generation (1966-1973) computer consisted of integrated circuits (IC) i.e. many transistors in single silicon chip. A single IC has many transistors‚ registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971)‚ fourth generation of computer evolution started

These include the desktop that is in many homes to the cell phones in your pocket. Even things like your car‚ dishwasher‚ dvd player‚ and even TVs include some form of computers. All this would not be possible without the invention of the integrated circuit or IC. This led to the creation of the Microprocessor or CPU (central processing unit) which acts as the brain of the computer. To better help illustrate the function and need for a CPU you must go back to the first all electric computers. Now computers

Change Plan: Circuit City Kara Burke Keller Graduate School of Management One major change that took place in the Circuit City organization was its bankruptcy and liquidation of its assets. I was unable to find any communications that occurred within the organization‚ much less externally to stakeholders. What I was able to find were many news communication pieces from third parties. The communications highlighted all the stages of this change‚ from the announcement of bankruptcy filing to

Q-Meter The Q meter is an instrument used to measure electrical properties of coils and capacitors. Mostly used in testing the radio frequency circuits. A Q-meter basically measures the Q (Quality Factor) of the circuit. It is also used to test the inductors‚ capacitors for their high frequency inductance‚ Q ‚ capacitance as well as ∑‚ tg δ value.
