Try it

Hold IN under the view for a long press, tap it for a short one: the demo counts the 32 pulses for you: pick 100× in the speed dropdown and watch OUT change (the box marked OUT turns red while the output is on). Press play under the view to watch a demo on a loop; touch any other control to take over.

How this design does it: A chain of five bulb T flip-flops (bulb + comparator each), each comparator toggling the next bulb; the last comparator is on for sixteen pulse windows and off for sixteen (level style, period 32).

Details: how it works, measurements and properties

In depth

It counts input pulses: the output's state repeats every 32 input pulses: after each pulse it is on for 16 of them and off for the other 16. In other words, it divides the number of pulses by 32.

Use it to do something every 32nd time, or to slow a fast clock down 32 times.

How to try it

Press play under the view to watch the demo on a loop (the badge reads demo with the step it is on; the same sequence is drawn as a timing diagram below). Touch any control to stop it and try the circuit yourself.

To try it: press and hold the IN button of the bar (or the cell tagged IN) to power that input; a quick tap sends a short 2-tick pulse.

Inputs are tagged in lime; the output is tagged OUT: the redstone lamp in that cell (the view adds it to show the output) lights while the output is on (the output strip by the demo badge shows its last 40 game ticks, 2 seconds). Drag to look around, pinch or scroll to zoom, step one game tick at a time with the step button.

Inputs and output over time

The input follows this schedule (the 3D view's demo plays the same). Lime: an input is on; orange: the output is on (taller = a stronger signal, 1 to 15). Time runs left to right in game ticks (20 ticks = 1 s).

Swipe the diagram sideways: the whole sequence lasts 4489 ticks (3 min 44.45 s).

N	32	how many input pulses one output cycle takes
output	level every 32 pulses	how the output shows the count: toggles (flips every N), pulses (one pulse every N) or level (its state repeats every N)
counts	one pulse per N
on	16 of 32
