Yes, I can help you. Which MCU are you using for the project ?

You can also contact me at <snip>

or you can PM me if you don't want to show your code.

I'm using arduino uno but the output pin in arduino only enough for one 7 segment only... so for the rest three 7 segment i'm using same output as the first one. So how can i make two 7 segment count in certain time while another two display '0'? here is my email <snip>

7 Segment display has to be multiplexed.
