TITLE : DIGITAL CODE LOCK

INTRODUCTION
Here is a project called ˜Digital Code Lock using AT89C2051'. LCD is used for display and a keyboard is used to input the keys. This project source code is written in C.This a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4×3 Keypad (please see the sc ....etc

Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc

ELECTRONIC CODE LOCK

The aim of this project is to interface 4x16 LCD, 4x4 Matrix Keypad, Motor and Power Supply with 8051 Microcontroller and provide a simple low-cost electronically operationlised door.

A keyless electronic combination lock is adaptable for placement on a door, and operates independently of any other locks and without a central control system. The lock has an 8051 Microcontroller, 4x4 matrix keypad for entering combinations, motor to move the door, 4x16 LCD to display the process of Electronic Code Lock. ....etc

A Brief Description:
This project is written in C language. Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.

ABSTRACT
Anti-Lock Braking Systems (ABS) are designed to maintain driver control and stability of the car during emergency braking. Locked wheels will slow a car down but will not provide steering ability. ABS allows maximum braking to be applied while retaining the ability to 'steer out of trouble'
The theory behind anti-lock brakes is simple. A skidding wheel (where the tire contact patch is sliding relative to the road) has less traction than a non-skidding wheel. By keeping the ....etc
