Hello all! I am new to electronics and set this as my first project, I am determined to see it to the end.
I am trying to make a LED 2 digit counter that is round, and has a wheel on the outside that spins clockwise to manually count up, and counter clockwise to manually count down.
Here is roughly what the device will look like.

And here is the trigger I decided to use to make the wheel work

I modified this up/down counter schematic..

Could you help me modify this schematic so it will work?
