EMBEDDED SYSTEMS
1.1 Introduction:
An embedded system is a system which is going to do a predefined specified task is the embedded system and is even defined as combination of both software and hardware. A general-purpose definition of embedded systems is that they are devices used to control, monitor or assist the operation of equipment, machinery or plant. Embedded reflects the fact that they are an integral part of the system. At the other extreme a general-purpose computer may be used to control the operation ....etc

Abstract

For numerous motion control applications, the limiting factor in the design of the motion device is a highly accurate and quick response. To achieve these performance characteristics, two approaches to the design are possible. The first focuses on the physical construction of the motion device, which includes increasing the mass and thus the rigidity of the system, as well as employing high-precision components. The second procedure addresses the software required to operate and control the system. By combining several advanced cont ....etc

DTMF Based Interfacing and Control of Induction Motor using TRIAC



The AC induction motor is the most commonly used AC motor in industrial application because of its simplicity, rugged construction, and relatively low manufacturing costs. The reason that the AC induction motor has these characteristics is because the rotor is a self-contained unit, with no external connections. This types of motor devices its name from the fact that AC currents are induced into the rotor by a rotating magnetic field.
Our project d ....etc
