I'm trying to wire up the LM324 using only op amp 1 to amplify a 0-5v input to 0-12v scale. I found I need to use a 7/5 ratio for the resistors on my negative feedback loop. I get the theory, I even built the circuit on a simulator and works fine, but I can't seem to hook it up right on my bread board.
Here's the LM324 Pin Diagram: Here's how I've hooked it up right now,
VCC -> +16V.
GND -> 0v.
Input 1 + -> 5v.
Input 1 - -> 33K-ohm Ressistor -> GND
Input 1 - (again) -> 47K-ohm Resistor -> Output 1
then Finally, Output 1 -> LED Strip (Expecting 12 Volts here, but getting nothing).
