Hello,
I'm developing a project for bank security.
I'm using at 89c51mc.
At port 0 ir detecter is atteched and at port 1 leds are connected..
As senser senses(ir) respective leds will gets on..

i need any innovative idea to use rest of the two ports...

Cant use lcd due to some limitations.
Thank you..

 

This is not really innovative. There are already alarm systems that can dial several numbers on an intrusion - http://home.howstuffworks.com/home-improvement/household-safety/security/burglar-alarm.htm

Hello,
my idea was to connect mc with the gsm modual..
When security breaks user gets an immidiate msg on his cell..

But as same time i need to make a backup ( if phone gets hanged or somting like that) and fortunatly one port is left after al the setup...
I need an idea for this port..

However thanks for repling bro..
I like the vids...
