Oct 17, 2022 at 0:47 comment added Gil Why not convert it to a schematic as you have wired it, we would understand that a lot easier. It is also much easier to follow your logic in that format. You can download several schematic capture programs for free. I use KiCad. Schematics are part of the basic language in electronics.

Jan 21, 2021 at 16:07 comment added Gerben displayNumber only show the number for 10µs. So you need to call this function a lot more times per second for you eyes to notice. You could also use a timer to periodically change between segments, but fast enough that it appears all two displays are lit at the same time.
Jan 21, 2021 at 15:00 comment added StarCat You could make it easier for anyone trying to help you by structuring the wires in a more logical manner (for example don't let wires of the same color overlap) and maybe enlarging the schematic (so that pin numbers are readable for example). It's very hard to understand at the moment.
Jan 21, 2021 at 12:48 comment added John Seong It's supposed to multiplex^
Jan 21, 2021 at 12:02 comment added PMF You are never touching the segment display anywhere in your loop() function. So if does something (like going off) but none of the LEDs act as intended (i.e. switching from green to red), then something in your wiring must be wrong or the pin numbers in the code don't match.
Jan 21, 2021 at 11:43 comment added John Seong I debugged; which turns out, all the connections are right however when I press the button the segment displays turn off.
Jan 21, 2021 at 11:12 comment added chrisl Please try to color code the wires more. With nearly all wires being green and overlapping at many places it is really difficult to follow the wiring diagram. Also you have some more components besides the 7-segment displays, that aren't really relevant here. It is a common debug method to remove all code and components, that aren't relevant to a specific problem, then getting the relevant problem solved and then add the rest of the code and components one by one, always checking for errors inbetween. You could try building the circuit for only the displays and check again
