2-Bit Counter (Up and Down)
A 2-bit counter that counts from 0 to 3! :D
Set "Count" to 1 to start counting and set it to 0 to pause the counter. Set "Increment/Decrement" to 1 to count up and 0 to count down.
Clock
there are three different clocks that i have built in this showcase,
they all have some of the same principal rules;
the buttons above the 4 digit bit inputs are to move the face below it up by 1;
the button off to the side on the first and second are used to reset the clock if need be;
the input next to the box labeled 'P' is to turn it on or off
they all have slightly different quirks though
the first one is the very first prototype of a digital clock that i have made
the second is a smaller design that i shoved the wires from the previous into their own bok to make it look nicer; this was the first legitimate one though.
the third and final clock is what i dub the mini clock because it is my smallest clock that i have ever made; i essentially made some tweaks to the wiring and then put that on to its own very small circuit, the mini has a toggleable reset and power
Counter
A completely original (4-bit) counter I made.

commands:
10001: Clock
00011: Do a OR operation*
01101: Do a AND operation*
01110: Do a NAND operation*
01001: RAM edit/read**
*Use number inputs too do the logic.
**Use data inputs edit/assign values to an 8-bit RAM. Use the R/W pin to read & write.

12hr digiClock
The set 1 function of #2 works in the sub-circuit but fails to work for the output pulse in the main circuit. This is troubling to say the least. So I've decided to change hour 12:00 to 00:00. If you don't understand what I'm saying, don't worry. This description is just a note to future me to fix this bug (if it even exists in the real world).
There's several buttons in the circuit. If you figure out what those do, the laws of time are yours to behold.
