In today's edition of unemlpoyement, I shall try to prototype operating multiple 7-segment displays using only 7 pins (+2 pins). In simulIDE, I use a counter, which switches between 10 inputs for every postive edge trigger. Here I short 5th pin with MR, since I only multiplex 4 7-segment displays.
Now to either get the parts for this, or rewrite this in zig. Stay tuned for more unemployment :))
