DTMF based Industrial automation and appliances control system

ABSTRACT

The term “Embedded” it self represents an inclusion of several independent devices in to a single chip, which is also called a system on chip. With the invention of VLSI technology it became possible to develop high speed, low cost, low power, and small in size type integrated circuits. The Micro controller, that used for this purpose is called IBP (Itty Bitty Processor) or embedded processor. The versatility of the micro controller can facilitate to extend its wings in to almost all fields, out of which, the industrial applications is one of the most important.
The multi task oriented systems that cause time delays, which may be inefficient in some application, in such case, the micro controllers which can play an important role as an embedded system design is more suitable one. Here, we design a general purpose embedded system application “TELECONTROLLED DOMESTIC APPLICAION” is the evidence for the efficient use of automation, and is constructed round the microcontroller and DTMF (dual tone multi frequency) receiver.
We found the software suitable for my project work is Kiel, a Micro controller programming tool for ATMEL and other embedded chips and it is also very simple to use and simulate.
The programming required for this project written in Assembly Level Program, compiled and simulated using Kiel simulator. All errors were removed successfully and final achieved our goal of project.
