I'm working on a project for school, and have a few questions about the pins. Basically what this op amp will do, is detect the power of the signal on pin 5 and adjust the LEDs from left to right to represent how "loud" it is kind of like a volume meter. My professor said the dotted line with the capacitor is not required to make the circuit work, and neither is the R_LO on pin 4. The schematic requirements says a 100K potentiometer is required, but where would I hook this up to the op amp?
