There weren't any chips but this is correct and it did work.
overview
For this project, I was required to build and simulate a 60 second timer. I made this so the ones counter would count from 0-9 then that would switch over to the tens counter. I constructed this so that it counted from 0-59. If i made it from 0-60 technically it would count from 0-61. Once the counter reached 59, it would reset to 0. I also integrated a switch into my circuit so that it would reset the counter to 0 at any point.
pld circuit
This is kind of like the DMV project because we used a ones and tens counter that switched each other over. However, instead of counting to 80 and pausing, this counter counts to 60, and then resets to 0
final project conclusions
This project extended my knowledge from the last project. I really understood the difference between synchronous and asynchronous counters. Synchronous counters are much faster and they don't have a ripple effect because they are connected directly to the clock. Asynchronous counters are slower and have a ripple effect because they require less logic. Also, '163 (74LS163) can only be an up counter, and '193 (74LS193) can be either an up or down counter and can be programmed to start with any number, but it has to be the next number in order to witch at the number you want. In order to create this counter, I had to make two separate counters and link them together so that the ones counter would switch over the tens counter until it reached 59 then it would switch over to 0. When I started making this project I used my DMV display counter and just made a few adjustments. I saw Justin's circuit, and his tens and ones counters were on opposite sides as mine, however, James had the same idea as me.
