yoo martin, thanks again, as said in my post, i have the stepper
already under control via a ULN2003A driver and a potentiometer.<br>
<br>
im stuck in the pd part, no problems with comport or the serial but with the pd patch.<br>

<br><br>With pduino you can send each bit pattern at once, don't set the pins<br>one at a time, it's too slow.</blockquote><div><br>
yeap, this is exactly what i will like to use pd for i was banging a
[counter 1 4] but im not sure about speeds and how to get to each of
the 4 pins that go from the arduino to the ULN2003A.<br>
<br>
thats why i was asking for some pd patch for troubleshooting the possible pattern secuences.<br>

<br>enough voltage or not using transistors, or transistors not fully on).</blockquote><div><br>
<br>
i guess is more related to the right pattern since the same circuit
works when i use a potentiometer, as said before i will like to try it
using the pduino if that is possible?<br>

I will try the <a class="wikilink" href="http://www.arduino.cc/playground/Code/SimpleMessageSystem">SimpleMessageSystem Library</a> maybe its easier.<br>
<br>
thanks again,<br>
