I'm trying to setup a buffer using the LM358 dual op amp. I'm supplying it 5V from arduino, connected ground to arduino ground. Input = Pin9 on arduino, analogWrite = 127 Input = Connected to output Output - connected to + of multimeter. Then I have ground from the multimeter to ground of the…

I'll have to look up why !

Hane a look here Power Supplies
Scroll down ! until you find multiple power supply
GrumpyMike is really Cool
