what kind of help you want…. 

[monam]

Our group decide to do a keypad, a LED, a buzzer and a siren, we wrote the keypad code, but we don’t have any idea about the LED code, because we want to do that when the siren starts to sound,  the LED will start from on to off, to indicate that someone is trying to stole our card, or we press any key to display the alarm, the LED have to start to run… how can we do that?

@monam : if you have been able to interface keypad, then interfacing LED is a child’s play. If not, check the LED and Keypad interfacing projects in 8051 section of this site.

The code they have given is in C..  however if u want code in assembly you can do yourself or search on google.
