So, I've just began working with circuits, and I want to build this color organ. It is powered by a 12v source. Audio signal comes in and is split through 3 filters then each of the 3 signals (high, mid, and low) go to a transistor which powers 3 different color sets of LEDS. It looks like a pretty cool project, but I had one question. Would there be a way to add more LEDs? I know from the calculator I could easily get 27 if I had 9 rows of 3 in a series and broke them up into 3 blocks of 9 instead of the original blocks of 4?
I just dk if the 12 volts are split up to 4, 4, and 4 into each transistor, which would not allow for a larger square array or if the 12 volts run through the whole circuit, if I would need to change anything (transistors or power supply) to increase the number of lights?
