Very simple question:
what is an object that can low pass filter floats (not ~)?
is there a searchable database on pd objects? googling only found this

iir, fir, median etc
from the mapping lib.

another way to filter floats is to do:

and make sure, that X + Y = 1 and bothe are 1 and 0.

Hello all, hello Roman,
I try your method with X+Y=1 and 0X1 and 0Y1
and your description for the patch.
So i get this patch. It seems that i get strange result, no ? Or i
miss something ?

Hey all,
I'm using the new Pduino 0.4beta2 and Firmata0.4beta3 with Pd-Extended

LEDs via the Digital Write pins 2-12. Each has the possibility to blink
at a different speed. What I've discovered is that if I have more than 6

X and Y are supposed to be the coefficient and _not_ the incoming
signal.
attached patch explains probably better, what i meant.

The blink interval is something in the area of 200-500 miliseconds,
certainly slow enough for the comport. Could it be trouble with some of

Hi, Derek,
One thought that occurred to
Maybe with 8 or more LEDs you are pulling too much current and the board is
resetting or doing flakey things because its power supply is glitching.
Especially if you are powering it from USB.

Hi Martin,
I checked the draw of each LED, and it's about 15 mA. Should be enough
when the Arduino can take 300 mA, but like I said the problem persists
even when all my electronics are disconnected. And so far I've only
tested it with one LED plugged in, trying each channel individually.
Attached is a diagnostic patch which demonstrates the problem. This
problem can be demonstrated using only the Arduino board with a single
LED (plus current reducing resistor of 1.5K) connected from pin 2 to GND.
At 7 simultaneous [metro]s, the on-board LED at Pin 13 starts to blink,
even

I'd really like to have a solution or workaround to this
There were bugs in that version. They have been fixed in the version
of Firmata that is included in Arduino 0012. Burn that version to
your Arduino and use the regular Pduino pd patches. Once I get a
spare moment, I'll update the Pduino .zip on my page.

Problem remains the same after upgrade. Looks like I or probably a
friend have to write some custom firmware for this project before tomorrow.

I'll take a look and see what I can find. You could also write an
Arduino firmware using Firmata as a library, then just support the
things you need to have working. Perhaps the timing of the analogIns
or something like that are interfering.
Look at the examples in Arduino, like
I am currently arduinoless, but once I get home tonight, I'll see if
I can find the root of the problem.

Sorry if this might seem ignorant, but would it be an idea to make

Hello.
There's a very easy way to do this in custom firmware with raw arduino code,
using a shift out chip
I used this a lot of times and actually I'm using right now in a project,
and works very fine. Uses only 3 arduino digital outs.
for example, in this beat sequencer...
