Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc

Introduction

The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube. It was a cold-cathode diode, a modification of theCrookes tube with a phosphor-coated screen.

A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitive ....etc

Kim Kardashian has revealed that she intended to start trying for babies just four weeks before she decided to split from her NBA husband Kris Humphries. The pair brought an end to their marriage after just 72 days, and it has been one of the biggest talking point in recent times. Many have been criticising Kim Kardashian by saying that the whole marriage was a setup. However, the TV reality star has revealed that she badly wanted to have some babies, and that they were about to try for the same just weeks before splitting.
One of the main re ....etc

CRT MONITOR cathode-ray tube



Disadvantages of CRT

They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion
Within a CRT a strong vacuum exists in it ....etc

More and more experimentsare now ‘PC-assisted.’ Alsoconventional acquisition systemsare very expensive. Since portablePCs are today common and a USB linkis a better solution than an old ISA bus,here we present an oscilloscope usingUSB port of the PC that operates at upto 10 kHz with ±16V input voltage. Ithas much more improved features thanthe PC-based oscilloscope and LEDscope for audio servicing published inEFY Dec. 2002 and Electronics ProjectsVol. 8, respectively. The oscilloscopeuses IC PIC18F2550 from Microchipas the main controller ....etc
