I am currently looking for a way to control a potometer via my computer. I have basic knowlege of electronics. This here: http://pdfserv.maxim-ic.com/en/ds/DS1669.pdf should work, i just need a way to interface it via the computer and since i have no knowlege of making programs or interfacing with the parallel or serial port i am asking for a little help. When im done with this project ill share it with everyone and i really think some of you will like it, as it can be applied to alot of different things. I just need to be able to change the value of the resistor and also maby have like 4 controlled outputs that i can use to hook up to transistors to turn the circuit on.
