Color organ v2.2 schematic
I've changed the values of the resistors R11 , R12 , R6.
This is for the amplification level of the signal.
I think that the previous values offered bigger amplification than we wanted.
So now we have more flexibility with the audio levels of the signal.
New values: R6 =10K , R11=4,7K , R12=10K
