I am building some audio devices, just getting into the DIY hobby for Audio and as my 1st project I am building a spectrum analyzer, EQ, Passive Pre Amp with a ton of inputs on it. I've got big ideas however I need to learn electronics, PCB design, and Microcontrollers.
This video shows some random numbers being generated by the PIC, used to simulate a single bandwidth segment of spectrum to be displayed by the LEDs.
