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

Automatic Room Light Controller [pic] INTRODUCTION This Project “Automatic Room Light Controller with Visitor Counter using Microcontroller” is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter

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

Periodic trends across the period three oxides Clare Smerdon Access to Higher Education Science 08/04/2015 Julie Day Periodic trends across the period three oxides Objective This experiment is intended to explore the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. Hypothesis This experiment will be investigating the following

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

Introduction The resistance of a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is
