ok so I'm working w/ this schematic.
http://www.uni-bonn.de/~uzs159/adsr2.png
i want to put an led on the other end of the last opamp. I want to have the voltage to the led to max out at the leds max brightness, i want it to get no higher, but i want the voltage to bottom out at the min brightness of the led and get no lower, how would i go about doing this, maybe put 1k resistor in parallel w/ the led and then a 1k in series w/ the cathode of led to ground?
idk help me please!
