toggle cycling multiple outputs from a single input

Archive: 10 posts


I feel embarassed to ask this because I suspect it should be basic, but how the heck do you toggle cycle 3 (or more) emitters using a single grab sensor?2010-11-27 23:32:00

Use a selector set to have 3 outputs then hook up the grab switch to the cycle input.2010-11-28 00:27:00

...the cycle input.

Which, if you're unclear, is the one on the bottom of the selector.

There's a cycle input? Well I never! That makes it nice and easy.

Thanks Zmauthe!

I even said to you that I bet it's a really simple solution that I was stupidly missing somewhere. Guess I should have listened to the tutorials instead of working everything out by trial and error.

Just out of interest though, if there had been no "cycle" input on the selector, how would you tech minded guys around here have set up the toggle/cycle logics in theory?

Without cycle, each selector output would have to activate the next selection when a button is pressed (using an AND gate), but you have to prevent the next selection from immediately activating the selection after that. You'd want the next one to only be activated on the rising edge of the button signal (the transition from off to on). You could try a counter counting up to 1, with the output connected to the reset. Shadowriver has a video showing one, he calls it a One-Shotter.2010-11-28 15:41:00

Handy tip - attach a combiner to the cycle input - the + will advance the selector by 1 and the - will retract the selector by 1. 2010-11-29 18:05:00

What use is a combiner when you have only a single input (grab sensor)?
