ABSTRACT Ultrasonic range finder using 8051 A 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

CHAPTER - 1 INTRODUCTION In this busy and competition world we cannot monitoring our elders (aged people) and patients continuously even though we have so much of love on them .By using advancements in present technologies we are developing this project to save time and user friendly system . The user has to press the respective button to get his service‚ and then the predefined message will be played through speaker. In general‚ most of the patients forget to take the appropriate medical course

Egypt’s economic policy during 2004-2008 is best described as a command economy due to the government’s involvement in the process of reforming economic policies that were hindering the country ability to grow economically. The government’s involvement did help boost the growth rate by liberalizing trade. Egypt reduced the tariffs‚ tax cuts‚ deregulation‚ and made changes in investment regulations to fuel their economic growth. Eventually‚ with these changes Egypt saw great economic growth. Big name

The fault occurring at what distance and which phase is displayed on a 16X2 LCD interfaced with the microcontroller. In this project we use a microcontroller from 8051 family which is of 8-bit. The program is burned into ROM of microcontroller written in either Embedded C or assembly language. The power supply consists of a step down transformer 230/12V‚ which steps down the voltage to 12V AC. This is converted

There are number of popular families of microcontrollers which are used in different applications as per their capability and feasibility to perform the desired task‚ most common of these are 8051‚ AVR and PIC microcontrollers. In this article we will introduce you with AVR family of microcontrollers. History of AVR AVR was developed in the year 1996 by Atmel Corporation. The architecture of AVR was developed by Alf-Egil Bogen and Vegard
