How to connect V+ and GND pins on a LM324N Op Amp

Question

I'm just learning to use Eagle software. I have a schematic that uses a LM324NE3. LM324NE3. Op-Amp. When I add this part, eagle lets me add 4 op-amp traingles to the schematic, but I can't figure out how to connect wires to V+ (pin 6) and GND (pin 11) because they are not shown on the schamatic diagram. My circuit actually requires +5 volts and -5 volts for the LM324. I'm using a MAX1044 to create the -5 Volts which will go to LM324 pin 11 (ground pin). How do I wire the V+ and GND pins on the LM324NE3. LM324NE3. ?

Hi Scott,

Use the INVOKE command to bring in the hidden power pins. Several of

EAGLE's libraries have the power supply pins hidden so you can use the

invoke command to bring them into the design and connect them explicitly.

Let me know if there's anything else I can do for you.
