[PD] pd2stepper round II

[alejo d]

yoo martin, thanks again, as said in my post, i have the stepper already
under control via a ULN2003A driver and a potentiometer.

im stuck in the pd part, no problems with comport or the serial but with the
pd patch.

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.

thats why i was asking for some pd patch for troubleshooting the possible
pattern secuences.


So if you get ticking and not continuous motion it usually means that

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?


If you can show a diagram or photo of your setup I could probably help

I will try the SimpleMessageSystem
Library<http://www.arduino.cc/playground/Code/SimpleMessageSystem>maybe
its easier.

thanks again,
