Project Update!

Hello friends,
the new and improved, update of "AT89C4051 as RTC" is available for download. instead of 16x2 LCD i am using 20x4 LCD and with the help of CGRAM area in LCD (type HD44780) i created digits from 0 to 9. which are double the size of the original clock. so clock looks much better and is more impressive.. few more bugs have been fixed.

so give it a try... go to download section and DOWNLO... Read Compelte post

Pins high is the normal state. You need a program to set them low
