clock

An input that flips itself: a square wave with period: from one rising edge to the next, ticking while the circuit is on screen. The reader pauses and restarts it by clicking it, and a paused clock shows ‖ beside its level. A cue starts or stops it through running:. For a clock the reader steps by hand, use a switch.
