ULTRA-SONIC DISTANCE METER. Introduction to Ultrasonic Distance Meter The project Ultrasonic Distance Meter is a very interesting and useful project for many industrial applications. In this project we have used the ultrasonic waves to measure the distance in between two points. The basic principal is based on the speed of ultrasonic waves in open air. We have used a microcontroller AT89S51 to transmit and receive ultrasonic waves through 40 KHz ultrasonic receiver and transmitters. By measuring

ABSTRACT The objective of this project is to design LCD digital oscilloscope for practical use. The basic concept for the project involves reading the voltage signal at the input and displaying it on the screen of an alphanumeric LCD. The input analog signals are supplied to the ADC(Analog to Digital Converter)‚ which are then sampled by it and the amplitude of the signal(voltage) is displayed on the LCD. Device Components: Microcontroller or processor: We used Atmega16- an Atmel AVR series

PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable
