Circuit design
Common questions about designing a circuit.

How do I turn a button into a lever?

 * Use a T Flip-Flop.

A button turns on each time it is clicked, while a lever toggles its output each time it is clicked. A T flip-flop is a circuit which toggles its output each time its input turns on, so it can turn the signal from a button into the toggle output of a elver.

How do I turn a lever into a button?

 * Use a Dual Edge Detector.

A lever changes its output when clicked, while a button outputs a pulse when clicked. A dual edge detector is a circuit which outputs a pulse when its input changes (either from off to on, or on to off), so it can change the toggle output of a lever into the pulse of a button.

How do I detect if two or more inputs are on?

 * Use a U2A Decoder.
