Hi there,
My group is currently working on a digital clock project. The clock must have seconds, minutes, hours, days and months and a reset button. Currently, we already have most of them except the reset button.
I just want to ask if there is a way to design a reset button for the above circuit and how to connect it to the seconds, minutes, hour's part and days and month's part to form a complete clock. If possible, can you simulate it in software or draw it on paper for me?
Thank you very much.

It appears that your trouble is in knowing how to perform a reset. Do you understand the datasheet?

 

Your design uses 74HC390 dual decade ripple counters and it has CLR inputs.
Can you not use the CLR inputs to reset the counters?
