How to Make a Digital Clock

[erictzhec]

Design a digital clock with the following functions:
• Displays hours, minutes and seconds
• Indicates PM by displaying the decimal point
• Enables the setting of hours, minutes or seconds by having the display increment at a fast or slow speed and then stopping at the desired value
• Without using microcontroller and microprocessor

you can CMOS 4000 series ic such as combining decade counter..but first u need very persistent clock input..

Whose home work is this?..

search google , you will get lot of circuits

without using micro controller i think the time will not be accurate and may not function accordingly.....
correct me if i am wrong...

Microcontrollers use clocks to measure the time and you can do the same by using the clock directly. No microcontrollers are required.
