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

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.
