:?
I am doing a final yr project of a telephone as a remote control. I am mainly concerned with the security features of it. All the sites that I have seen dont have this feature. Im planning on using a PIC16F84 to pass data from the DTMF-to-BCD converter to the 4 to 16 line Demux. Can the PIC6F84 be handy for a situation where I get BCD data to pass it on again for execution?
I need to use it for security features. I want it to FIRST aunthenticate the user before they can switch on any appliance, say by first inputting a 4-digit password, which will THEN activate the controlling circuit, allowing. after that for normal remote controlling (by pressing say digit a '1' or '2' up to '9' in DTMF mode which will be converted to BCD then to the PIC to go straight into energising the appropriate switch) to resume.
After that, pressing a '0' to disable the remote controlling system freeing the telephone line for normal use.
Can it work, and if so how?
IM STUCK! AND I AM NOT THAT GOOD IN MICROCONTROLLERS, BUT I AM A FAST LEARNER.
PLEASE HELP....
