Present project is designed using 8051 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compart ....etc

Why do we need to learn Microprocessors/controllers?
The microprocessor is the core of computer systems.
Nowadays many communication, digital entertainment, portable devices, are controlled by them.
A designer should know what types of components he needs, ways to reduce production costs and product reliable.

This article presents a class which can be used in both the client and server code. The class uses IOCP (Input Output Completion Ports) and asynchronous (non-blocking) function calls which are explained later

With this simple report you could understood :

Service or connect to multiple clients and servers.

Send or receive files asynchronously.

Create and manage a logical worker thread pool to process heavier client/server requests or computations.

It is difficult to find a comprehensive but simple source code to handle client/se ....etc

ECTION USING 8051
MICROCONTROLLER

Flame detection using 8051 microcontroller is an embedded system application which can perform task of detecting fire and temperature to prevent disasters without continuous human monitoring. The behavior of this system is based on LDR sensor information. It uses LDR and LED which gives input to microcontroller by means of sensing. When the system is powered-on, it detects the Light by using LDR, based on this the microcontroller LED is glowed. ....etc

Introduction:

A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps.
Stepper motors are similar to switched reluctance motors (which are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.)

Fundamentals of operation


Stepper motors operate differently from DC brush motors, which rotate w ....etc
