simple ultrasonic range finder using 8051 microcontroller is presented in this project. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object‚ then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller accepts this signal‚ performs necessary processing

A microcontroller (sometimes abbreviated µC‚ uC or MCU) is a small computer on a single integrated circuit containing a processor core‚ memory‚ and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip‚ as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications‚ in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in

Visual Basic and Databases 1. Introducing Visual Basic and Databases Preview In this first chapter‚ we will do a quick overview of what the course entails. We will discuss what you need to complete the course. We’ll take a brief look at what databases are‚ where they are used‚ and how Visual Basic is used with databases. And‚ we’ll review the Visual Basic development environment and the steps followed to build an application in Visual Basic. Course Objectives 1. Understand

My definition of "old-timer" would be someone in their 70s.80s. So I would take the age at which Mr. Old Timer was raising his children‚ which was apparently when he would have been at the age to determine respectfulness of his own children. Let ’s say 25 years old. That generation would have had multiple children by then. If he was born in 1940‚ he would have been 25 years old in 1965. I would take data from his geographic area from the years 1965 and 2010. Each group would have 20 people

MICROCONTROLLERS A microcontroller (sometimes abbreviated µC‚ MCU) is a small computer with similar components as a standard personal computer only integrated on to a single chip and usually dedicated to a single task. The fundamental components include a processor core (C.P.U)‚ memory‚ system clock and programmable input/output peripherals. Microcontrollers are designed for embedded applications‚ in contrast to the microprocessors used in personal computers or other general purpose applications

What was the main reason for Italian Unification? In 1815 after the battle of waterloo and the end of the Napoleonic wars‚ the victorious powers met to discuss what to do to at what became to be known as the Congress of Vienna. To ensure that war on the same scale never broke out again they decided to make very little changes to the current map of Europe‚ except strengthening all of France’s neighbours. I was agreed at the conference that the ruling powers should meet in the future whenever
