i see two possibilities (probably there are more):

using the parallel port: you need the external zexy ftp://ftp.iem.at/pd/Externals/ZEXY , which contains the object [lpt] to get acces to the parallel port. on linux, you need to be root to get permissions, on windows you need to installl something addidionatlly (have a look at the helpfile of [lpt]).

using an arduino: the arduino is an open source and 'open hardware' microcontroller board, which can also be used as an i/o-interface board for pd. you can use its digital pins as digital outs, which you can control from pd. in order to use it as an i/o-interface, i suggest to upload hans-christoph steiner's pduino-firmware to it. more about the arduino: http://arduino.cc more about pduino-firmware: http://at.or.at/hans/pd/objects.html

I'm interested in using PD to create a sequencer which would control a series of Transistors via a Cat5 cable.

any thoughts?

I am fairly new to PD, so I thought this would be the best place to get feedback.
