Hey Guys,
So I'm putting together a Pork Barrel and on the new boards there is an LED that pulses with the rate of the LFO, which is awesome. There is also a spot on the board for a regular "I'm On" LED. I was thinking that it would be awesome to use a RGB LED so that it always glowed blue, but pulsed to purple or yellow with the rate of the effect. This is what I'm thinking. I'll probably use an LED with a common cathode. I'd put the blue leg in the positive side of the "On" LED, and the red leg in the positive side of the "pulse" led, leave the green leg out, and then which ground to I tie to? and do I need to put another 4.7k resistor in addition to the one in the board before it goes to a negative terminal since I'm having two currents into one LED?
