DESIGN A SPEED CONTROL OF DC MOTOR USING FUZZY LOGIC AND IMPLEMENT USING ATMEL IDS 6.0
AIM:
The aim of the project is to design a DC Motor using Fuzzy Logic using VHDL tools and implement it in programmable FPGA.
THEORY:
There are many conventional techniques for the Speed Control of DC motor. Some techniques like fuzzy control involve modeling of control of skins of a human expert and hence the present work is on a fuzzy based speed control strategy for DC motor. The contr ....etc

Some bicycles and exercise bikes are equipped with a little computer that speed and distance etc. displays. We now want some spinners (stationary bikes) can be equipped with a little computer. But we want the distance traveled is added, so that we for instance with 6 people at once can cycle 80km, and once we get this one alarm. Number of cyclists and distance to be introduced to, and everything should be wergegeven on an LCD screen ....etc

Please help me to interface rishabh energy meter EM 1340 with Arduino Uno. I have tried using ModbusMaster Library and SimpleModbus Library for coding in arduino. I have build RS485 to TTL converter using MAX485 IC and circuit which is given in SimpleModbus Library . I can share the code with you . My problem is that i am always getting Timeout Error . I checked on DSO the query at the converter end is not what is accepted , I mean when arduino sends query the message in form of square wave but at converter end their is loading . Please tell me ....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
