Clock

Clock[]
represents a clock variable whose value cycles continuously from 0 to 1 once per second when it appears inside a dynamically updated object such as a Dynamic.

Clock[t]
cycles from 0 to t every t seconds.

Clock[v_max, t]
cycles from 0 to v_max every t seconds.

Clock[{v_min, v_max}, t]
cycles through the range v_min to v_max every t seconds.

Clock[{v_min, v_max}]
cycles through the range v_min to v_max over the course of v_max-v_min seconds.

Clock[{v_min, v_max, dv}]
cycles from v_min to v_max in steps of dv, spending dv seconds at each value.

Clock[{v_min, v_max, dv}, t]
cycles from v_min to v_max in steps dv every t seconds.

Clock[vals, t, n]
goes through the cycle only n times, then always yields only the maximum value.

MORE INFORMATION

The base for all times used by Clock is the creation time of the cell in which Clock appears.

Clock[Infinity] gives a value that ranges from to at a rate of one unit per second.

Clock[{v_min, Infinity}] gives a value that ranges from v_min to at a rate of one unit per second.

Clock[{v_min, Infinity, dv}] ranges from v_min to in steps of dv, spending dv seconds at each value.
