(Until the end of summer, this will constantly be updating until I'm 100% finished with it)
For this project I am making a 20x32 LED matrix and an audio amplifying input to interact with an Arduino DUE. Like the title says, this contraption will be able to analyze audio frequencies and break them down into bands that can be displayed and visible without the need of an active desktop or laptop.
The general purpose of this instructable isn't for you to recreate my project to the fullest, but for you to take ideas and knowledge from mine to incorporate into your own projects. I will still try and post step by step details of how I made mine, but feel free to message me your questions and I will try and offer advice or suggestions pertaining to types of matrices, arduino, or audio analysis.
[AS OF RIGHT NOW, THIS INSTRUCTABLE IS FOR PERSONAL SUGGESTIONS AND UPDATES FOR MY PROJECT UNTIL COMPLETION]
Step 1: Currently Working on / Help Needed
Soldering GND lines on matrix
Soldering V lines on matrix
I would appreciate any suggestion for:
-an audio amplifier setup which stays in between 0-3.3v for the DUE to examen
-a push button which changes the spectrum display
