Electrical measurement of quantities plays a crucial role in the real world. Measuring voltage is one of the main tasks for developing large number of applications. This paper is focused on design and development of digital voltmeter using different techniques. It has been shown how to develop a Digital Voltmeter (DVM) from simplest type to professional digital voltmeter. Different types of techniques...
We present the architecture and design of a general purpose robotics development kit, called X10ABOT, which aims to facilitate the rapid development of robotic solutions to a wide variety of problems. Robotics kits of this sort are usually aimed at casual hobbyists and children, and as a result, usually have severe limitations in the number of sensors and actuators that they can manage. In contrast,...
We describe the implementation of a real-time control system that manages arrays of pumps, valves and pressure transducers as a subsystem of a simulator for cardiac surgery training. The subsystem is responsible for maintaining an appropriate fluid pressure in the aorta of the heart, and for circulating fluid around the heart, in a manner consistent with a cardiopulmonary bypass machine - both before...
This paper studied about micro controllers interaction using RS232 as a communication tool and C to programming the interaction. PIC18F4520 will be used in this prototype and MPLAB as a software tool. Before run it into the real hardware, some simulation must be done to make sure all the hardware connection and software writing is correct. Proteus 7.1 has been used for the simulation purpose. The...
Microcontrollers are widely applied in the field of industry to solve engineering control problems. The increased use of microcontrollers makes microcontroller course necessary for electricity related speciality. A new simulation software package for microcontroller, Proteus virtual system modelling (VSM), is introduced for industrial and educational use. Proteus VSM combines circuit simulation, animated...
Software chip is designed to present a study software platform without support of hardware entity by simulating hardware chip operating function. The paper introduces the concept of software chip, and presents software chip design methods. When designing a software chip, specific and related things or controls are chosen to substitute for the abstract functions of the chip, and signal flow trend and...
Recent developments in microcontroller, radio transceiver, and energy harvesting device design now permit wireless sensor nodes to operate indefinitely from power scavenged from their environment. Many algorithms for conventional sensor networks assume that nodes run directly from non-rechargeable batteries and therefore attempt to conserve energy rather than carefully exploiting it when available...
