Hello Friends
I want to make a project of four digit Up and Down counter by manually press the button of the up and down. And it will show the digit in the seven segment display. and one more thing is that when we restart that time it have to show the last digit which was before restart. Plz help me if you any one have the circuit of this project or any other useful links. plzz
 

hi,
Look at this link.
Add another digit to make it 4 and if required, reconfigure the 555 as a monostable to give a well defined clock pulse.
