• Scoreboard - Updated Schematic

    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:
