Subwoofer to control LED-Strip - Help needed
Hey guys,
Been searching the internet the past few days and I think I've found what I need. But since I'm pretty new to all of this so I thought I'd ask you guys if I'm doing it right.
Basically, I now have an RGB controller to control a common anode(i think?) LED-strip...
Now I want to use the connection from my amp to my subwoofer to somehow control the power that goes to the LED-strip, as to make it 'blink'/dim to the bass.
My solution would now be to place a transistor in the "question mark-circle" from my drawing; connecting the base to the subwoofer-wire, the powersource from the RGB-controller to the collector and then the emitter to the LED-strip.
If this is the right way of doing it, my remaining questions are:
- Which transistor do I need?
- Do I need resistors?
- Can I use a pot or something to control sensitivity?
