Real Time Clock using CAT89C4051

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
