I learned how to do this in college: courses are Electronics 1 and 2, and Digital Logic, which ended in building an Arithmetic Logic Unit on the computer in software then uploading it to an FPGA, this one which cost $10.

Textbooks for these subjects can teach you. Also, you don’t need all that difficulty: 1) practice passing data from A to B. This is after learning some electricity, but you just want to catch some input, stop acting, then replay it: switch, to charge a capacitor-and-resistor, that unloads on an led after a few seconds. This is the entire principle of a computer, in a single action! I’m also sending Magical Help, since I’m an Angel. Take care!
