Countdown timers can be constructedusing discrete digitalICs including up/down countersand/or 555 timers. If you wishto incorporate various facilities likesetting the count, start, stop, reset anddisplay facilities, these circuits wouldrequire too many ICs.Here is a simple design basedon 20-pin Atmel AT89C2051 microcontrollerthat performs countdownoperation for up to 99 minutes withtwo 7-segment displays showing theactual time left. During the activityperiod, a relay is latched and a flashingLED indicates countdown timing’ ....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.
