here is my problem:

i want to control 4 remote controled electrical sockets via pduino and my arduino uno.
the pure data patch is a simple noise gate, to trigger a signal for every remote controle socket bye turning them on and off. Anyone who has some experiences with that? some solutions? It´s an art installation...

thanks for anykind of help!

He everyone,

this is my first attemp on pure data. I´m trying to build a program for frequency-analysing using bp~ and i am stuck here...i guess there are several better ways to solve this task.

To give you some background about the project:
i want to mic noises of the citiy and visualize them. Therefore i want to control about 4 fans over an arduino-board, which respond to different frequencies by turning on and off and blowing up a textile above the fans... so the left one is responding to low frequencies and the right one responding to high frequencies and so on...
the patch should work with soundfiles as well as with [adc~]

The patch i made uses bandpass filtering and converts the signal with [unsig~] to get a float for a comparison...(by th way, what does this float i get out of [unsig~] tell me?i just heard of [fft~] and [sigmund~] but i am not sure how to use them in my patch.

I know the patch doesn´t work well, but maybe you have some usefull suggestions? Would be nice, if you could have a look at the patch!

cheers

thanks for the help, sebfumaster!
i changed some parameter of [threshold~] and now it works pretty good. It´s good to know with the 86 values of env~...helped me a lot!

thank you for the hint sebfumaster!

I changed the patch...it works pretty well i guess, but maybe you could have a second look at it?

When i do a frequency-test with the attached file from 100 - 10.000 Hz, the bang buttons should be triggered from left to right and not in a messy way. Any solutions?

Is it just the wrong parameters in [threshold~]?
