Microcontroller Based Caller ID (AT89C2051)

[Binu]

This Project can be used in home, shops, offices etc. It keeps tracking of both Incoming and Outgoing Calls. It has a built in Caller ID. The incoming and the dialed numbers are displayed on the LCD display. The system will display the numbers over the LCD display.
The Microcontroller is used to control the whole system it completely control the LCD display and the DTMF decoder. It gets the numbers through the DTMF decoder and display it over the LCD (Liquid Crystal Display).
Program: caller.zip

i will try, you can also try. i can help you. You should interface both RTC and EEPROM for storing the Time and the numbers.

a RTC shouldn't be needed as part of the callerid (here) is time, unfortunately this callerid only seems to do DTMF and my callerid uses Bell202

This project is only used to display the dailed and incoming number.

Hi Binu as you told earlier it would be very attractive if you add an rtc and eeprom...Can post the improved version.......the commercially available CID (those china made for 80 bugs)are really attractive but lasts for only a couple of months..I have purchased 2 of them and its dead now...

[Binu]

sure i will try to make it with RTC & EEPROM

[JOHNHONAI]

Thanks for your reply. you are really great..... man.....these days its hard to find a person like you....
