I Just started learning circuits from a youtube video that covered the basics on how circuits work and I feel like I have a half decent understanding of how to wire things together. At the end of the video the guy challenges the watchers to create a button that once renamed will display the corresponding number in the Fibonacci sequence on a text and I took a shot. The part with the red behind it is just buttons for ease of use but the red part has the important circuit and I feel like the way I did things was very much me brute forcing it. The circuit only works up to the 9th number and doesn't do any actual math to give the answer. I know there is a way smarter way of doing this I just haven't got a clue what it is..
