door password lock using (AT89S52)

[Ave]

Hi guys. I want to build a door password lock by using six7-segment LEDs. I have 4 switches, one is to choose the number and the other is to move to the other 7-segment, the otherh one is to enter and one again is to cancel. How do you think about this idea? waiting for your answers…

why dnt you use 16^2 LCD TO display the password ?? instead of 7 SEGMENTS it can be goes long…..

with no key pads although its simple but its not user friendly

make a project using 16*2 LCD ant uC(pic,atmel,arduino) and some solenoid switches etc
