i am using arduino and try to use digital inputs to trigger gemwins.

when there are continuous signals coming from arduino, the signals will trigger one set of reactions A. when there are NO signals coming for over 3 seconds, then it will STOP/END all reactions in A, and switch to start another set of reactions B.

now i get 2 sets of reactions ready, however, i don't know which object(s) to use so that signals would switch modes from A > B. i can only get both A and B start working when signals start to pour in. i have no idea how to switch from A > B or B > A.

wondered if anyone knows how to do this?
thanks in advance

it's hard to give an advice, since i don't really know what you want to do... but did you have a look at [relay] or [route] or maybe [switch]? setup a conditional task, that changes the state of route? maybe post a little example patch (since we are in the patch-subforum (*gg*)), then it's maybe more easy to figure out, what you exactly need...

I've never used arduino, so I'm not sure what exactly it sends. Is it a continuous signal, like an audio stream, or is it more like intermittently repeated messages?

I think you want to take advantage of [delay] here. Attached is a patch that works well for messages. I made a signal variant of it using [snapshot~], but there might be a more accurate way to go about it if timing is important.

thanks for the input!!
it is close what i am trying to do
now i am changing parts of it to see the differences it'll make, modifiying it to fit my goal.
i don't know if its the right way to learn cos i don't understand all the math/ logic/ meaning of those objects in "help patches" or "flossmanuel". it's exhausting, too time consuming (and frustrating!) to open all other patches and try to change them to see what differences they make....
any other better way to learn pure data? i ahve been doing it for 2-3 months, but don't think i am picking up much. wish there were classes to learn it properly!

have you checked out http://www.pd-tutorial.com/ ? i think, there are some good tutorials...

thanks, will have a look!
