Scoreboard

Hey Guys,

I have finally updated the scoreboard schematic to make it accurate and correct. Here it is:

The PCB part of the scoreboard is still in progress. A few weeks ago I got the PCB board and soldered all of my components on to the PCB board. Unfortunately it did not work and realized I made a mistake on the schematic. So I fixed it and could not buy it because of the Corona Virus in China (I used JLCPCB to buy PCB board). I am fairly new to PCB board and still learning it to this day. I also am trying to fix the PCB board to see if the functionality worked. I suspect that I arranged the switches wrong. However, where I live, it is cold outside so I cannot open the windows, which leads me into a stand still. 

I want to give you guys an update and sorry for putting you guys in the dark.

I will give you updates as soon as the corona virus is done and I managed to fix my mistake.

I drew up a schematic for the scoreboard. Here it is. I have come a long way in drawing schematics.

[Edited] I have not put in the PCB board yet. I have changed the schematic but I will put it in a different log once I tested it and confirmed that the design worked.

I have stayed up until 1:30am which is last morning to figure out how to get the scoreboard to transition from 9 to 0 and vise versa. at first I used a bunch of logic gates and a flip flop at first but it is all in vain. Then I realized that I was overthinking this process. I need only 4 logic gates and three output with the first output at the and gate and the fifth output at the load pin of the sn74ls169bn. I did trial and error and intuition to get the logic output right. I test it out and it worked. This is the last part of which I want to implement into the circuit. All I need to do is to draw the schematic and the PCB board. 

Here is the video of the circuit:

Here are images of the circuit:
