musical water fountain using microcontroler pdf

Introduction

Musical Fountains fascinate me. In a musical fountain, art and engineering come together to create a piece of beauty. An aesthetically designed fountain and a controller together can create a symphony with water. Our final project is a musical water fountain loosely based on the fountain in front of the famed Bellagio hotel and casino. The basic idea of the project is to take an input from an iPod (or any sound source), sample the sound and break it down to different sequencies by ....etc

I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc

Abstract

Large grocery stores are nowadays used by millions of people for the acquisition of an enlarging
number of products. Product acquisition represents a complex process that comprises time spent in corridors,
product location and checkout queues. On the other hand, it is becoming increasingly difficult for retailers to
keep their clients loyal and to predict their needs due to the influence of competition and the lack of tools that
discriminate consumption patterns. This paper gives the pro ....etc

Abstract

Programmable timer is a microcontroller based machine. It is controlled by a microcontroller PIC16F84 a RISC processor. The presented topic is a programmable timer and time is set by a user through a switch, switching/alarm will be occur after a set time gap. Time can be selected in second and in minutes also according to requirement. Earlier the ....etc
