help needed on LED music box Answered
I want to build one like https://www.instructables.com/id/Music-LED-Light-Box/ , but with some LED only blink to bass (low range sounds), some to mid range, and some to only high range. Take this as an example: https://www.instructables.com/id/Music-Flashing-LED-Lights-how-to/ except I still like the idea of running through a mini jack.
I've done a lof reading and many people have suggested using inductors as low-pass filters. New to electrical things, I am really unsure what to do.
My design in mind is with 24 LEDs, 12 blink to bass, 8 blink to mid range, and 4 blink to high range. I'm planning to use a 12v DC charger with LEDs specs of 30mA forward current, 3.5V forward voltage. I understand having a VR will make the LEDs more consistent.
Can someone possibly draw me a schematic with the right resistors and inductors? help would be greatly appreciated.
