I gonna introduce myself!
I'm studiying how to build guitars.
For the end of the year project, I want to make an electric guitar. But an unusual one. That's the problem.
I mean, there is the situation. I want that, when one of the magnetic microphones get a signal, the LED stripe is turned ON.
And I need your help:
I know when a magnetic microphone gets a signal, it produce a (really weak) electric current.
But I don't know how to make this LED stripe shine at this only condition.
I looked at peak meters and stuff like this, but I'm a big noob in electricity/
In some forums, I saw mentionned audio sensors.
But I thought I could do something easier, like amplifying the current out from the mic then put that current into the LED so it will light up,
but I have no idea how to do this.
HELP, PLEASE
I'm sorry for the possible mistakes, I'm french.
If anyone could offer any help/advice, that would be really appreciated!
I think depending how you wanna do this, a msgeq7 ic would work well,
it would take the total output of the mic/mics and it outputs a multiplexed value for 7 audio bands,
you can then tke those vlues and light up leds according the strengths with pwm
I've used it for 3 channel light shows to general music but I think it would work well in your case
if you need code I got plenty
