Electronics

Most circuits that I've made so far in minecraft are using alot of basic logic gates. But as you progress you will need more advanced gates such as flip-flops. So at the moment I am trying to learn what flip-flops are used for. The T Flip-flop is pretty much the only one I have ever used before in my builds where I want to open and close a door with the same button, and keep them open with the push of one button.
