What is the best way to connect these modules?

[yes7]

Hello, I am working on making a project with a 4 digit seven segment display, a tilt ball switch, a piezo buzzer, a lithium battery, an elegoo uno r3, and a "elegoo prototype breadboard expansion module". I am curious and seeking help to find the best way to connect or solder the connections to the right pins without it looking ugly whilst still fitting in the 3d printed case I printed. The project is going to have a few diffferent modes, which will be switched with the extra button on the expansion module. The modes I am currently thinking of adding are a stopwatch, timer, clock, tally counter, maybe a game where you try to stop the timer at as close to exactly 0 seconds without going into the negative, and a dice that rolls when you shake the project(you could roll up to 4 dice or just 1, or 2 2 digit dice, or have it choose a number from 0-9999, etc.). These are just ideas, they don't all have to be implemented, at least not immediately, and I will try to figure out coding later(even though it'll be really difficult bc I suck at coding). For now I just need to figure the best way to solder or connect the connections to make the hardware work without it being loose, falling out, not fitting in the case, or looking bad. The only soldering I have done so far is solder the modules into place. Here are some pictures.

Any help would be very, very appreciated!

I would figure out the coding (at least the structure of what you want it to do) first before access to pins becomes more difficult after soldering.

For the functions you mention a RTC would be required. At least a time keeping library like TimeLib.h

The hardware will only work based on what you tell it to do. Good luck.

How do You intend make the LED display run? Any driver?

I would suggest drawing a simple schematic showing how you intend to wire it, not a frizzy picture. You posted a lot of pictures, although nice none of them useful to me. Also post links to "Technical" information on all of the hardware items. You state you have a "lithium battery" and all the other parts looking for a problem. How did you size the battery and how long is it to run on a charge. What do all of these modules etc require in current. That information and more will be in the technical information. This will not be a weekend or two project expect to spend some time with it.
