Hi,

Is it possible for me to add burglar alarm(simple buzzer) and light sensor module to the PR25 RFID door lock?

Hi,

It is possible but you will have to do some manual hacking and soldering.

Hi,

I am using IC16F876A for this. I've been told that there are 3 pins available but I don't know how to see which 3 pins are available from the datasheet. Sorry I am noob for programming stuffs. Can anyone help me?

Check the schematic first, see which pins are not in used. Those are the pins free for other usage.

There is no easy way, every need to learn.
