Hi all. I have this university project I have to build, I have to build a counter that is preset to a value 42 and count up and down between 42 and 0. I have been working on it for weeks now but it's not coming alright. I am struggling with presetting the counter to 42, has anyone done a similar counter? Please help.

Show us what you have done so far.
Show the schematic of your counter.
