New to the forum and new to Arduino in general,
I just wanted to get some help or if someone can shoot me in the right direction if this project has already been made.
I'm using an Arduino nano.
What I'm after is essentially making an LED get brighter to the volume of a guitar.
So the analog side of it would be the guitar signal going through an op amp to boost it up to a signal that the Arduino can read a little better which i can map to 0 to 1023 in the analog input.
So when i strum the guitar it will be picked up by the Arduino Nano and output a PWM to an LED to the same velocity/voltage as the guitar, (So if i strum quieter it will be softer, and louder it will be brighter).
Is this something that already exists in code i can see and deconstruct/alter?
Its essentially a envelope follower, and seems like something that exists already i just can’t seem to find anything as I’m having trouble on getting this code started off.
Thanks for your help.
