T tim_l_012 New Member May 23, 2003 #1 Hello to all readers, I have been looking at this fan monitoring article: **broken link removed** And I want to know what are the alternatives to the IC that the author uses. The IC is the ULN2803 from Jameco, but I couldn't find it anywhere. He describes it as a 18-pin IC, but I am not sure if I can use any 18-pin IC or not. If someone could help me out here it would be very helpful. Thanks in advance,

I have had a look at the online product listing, and i have foun a 7 Way Darlington Driver. I did a search for ULN and thats what I got. Could I use that? http://www.dse.com.au Thanks in advance,
