During the planning stages of my MAME project, I have repeatedly run into instances where I did some research to find the answer to a problem. While this has helped get the project to it's current state, it has left a lot of grey area in my head as to what exactly was taking place in the guts of my arcade. When I ran into a particularly difficult problem with the trackball wiring, I made the decision that it was time to start learning at the beginning with boolean logic, binary code and ohms law.

I've learned a lot about the foundations of electrical engineering so far and I expect to have a substantial arcade project update soon.
