wireing a 741 opamp
greetings all,
ok heres the issue, I'm trying to build a light sensor for my robot, I have a pretty good desogn with a 741 diferentiator circuit, the only problem is that I want to have it from just a standard DC powers supply. However I don't know and can't find anywhere on how to wire it so I get the neccesary -9v on pin 4. All the wireing diagrams I've found just say to have a -v but dont actualy say how to obtain it.
