Hello friends, here is a clock project where CAT89C4051 is used as RTC. LCD is used for display. Using CGRAM area of LCD you cn create cistome characters. Here you will be able to see big and better digits in LCD. The digits are twice the size of the normal digits.
PCB design for project is also given below. A nice PCB with single layer design. This PCB is recommended for the above project
The silk screen is not so good. but you can edit it as you want and make it look better

whether this is wrkin in real or not……..
I would add Real Time Clock IC PCF8583 and battery power only to RTC IC.
pls send the source code and the lcd configuration of the project digital clock with calender. thanx.
Awesome submit which has received me considering concerning the prospective of the idea. Truly truly awesome.
pls send the source code and the lcd configuration of the project digital clock with calender. thanx.n all d details
PLZ SEND THE C PROGRAMME OF Real Time Clock using CAT89C4051
Hi Sir,
