i wanna ask what is the name of the ic : ULN2803 or ULN2003
can we use Uln 2803
The picture you have is of a ULN2003 yet you talk about a ULN2803. Since the printer port is pretty much dead, you and your readers might be interested in a DLP-IO8 data acquisition board. It is USB and has eight I/O right on board. It's is VERY easy to control. I just made the switch - http://sparky3489.webs.com/pcinterfaceproject.htm
