1. The Basic functionality and applications of the project
I used to have this dream of a "computerized home" where a benevolent computer, on a piece of plywood on the wall in the basement somewhere, would oversee the lights and heating, turn on radio or TV when interesting shows come on, make voice announcements of important reminders and so on. I would be able to control this wondrous machine with a remote control from anywhere in the house, or call it up on the telephone, or push buttons on a locally wired keypad.
Imagine having the ability to call home while on the road, and by issuing simple commands, control devices inside of the home, such as lights, security systems, and air conditioners, as well as perform household tasks like vacuuming, picking up the mail, or just about anything.

12. Basic functionality of the project
When the microprocessor has finished counting about 3 rings,

13. Basic functionality of the project
When the microprocessor has finished counting about 3 rings,
A signal is sent to the On/Off hook chip to electrically change the impedance on the line,

14. Basic functionality of the project
When the microprocessor has finished counting about 3 rings,
A signal is sent to the On/Off hook chip to electrically change the impedance on the line,
generating a call answer (Off hook).

15. Basic functionality of the project
After the call in picked up,

16. Basic functionality of the project
After the call in picked up,
Telephone keypad tones are received through the connected line.
The DTMF decoder is used to decode the single tone into a 4 bit code.
The code is then sent to the microprocessor which is used for:
