Triggering Filestream using RS232?

[exelrex3]

Hey there,

I’m just getting started using vvvv so this might me an easy question for you guys. But I just can’t seem to get it to work.

I’m working with an Arduino and a motion sensor which sends a “1” to vvvv whenever it detects Motion. Everytime it doesn’t detect motion it sends a “0”. So whenever something is moving I want vvvv to play a .wav file all the way from start to finish. And only play again whenever something is moving again.

Right now I managed to get the signal in vvvv and it starts the filestream with audioout, but only for a very short time as Arduino is sending a “0” straight after which stops the audio again.

How can I trigger the filestream to play the audio once as soon as a “1” comes in no matter if there’s a “0” afterwards? And how do I reset the audio so it starts again when something’s moving again? Right now it only plays once if I start it with a toggle and then it’s over.

Thanks for your help, I really appreciate it :)

Don’t send a “0” from arduino. I dare to say that the general logic of your program could treat “0” and “” quite as the same output.

And how do I reset the audio

the node should have some pin signaling the end of file or the time reached by player, so it would be a framedelay (see helppatch) with a togedge node, for example, linked back to reset pin.

this can be done with a FlipFlop node. once you get a “1” you set it and when the file is finished playing you reset it. this involves a FrameDelay node:

Oh thank you guys so much, that was really helpful and it’s working just like it should now :)
