Part three of a multi-part blog post on building a MIDI synth instrument.
The basic idea is to use 3 Arduino's to make a visual / sound instrument.
Arduino 1) Send control data.
Arduino 2) Generate wav audio from MIDI input.
Arduino 3) FFT EQ visualization.
This shield will take WAV input & break it into 7 EQ ( FFT ) spectrum values which you can use to drive basically anything Arduino.
I'm going to stick to LED's.
LET'S BEGIN !
Solder on breakable headers.
And you might say, "This REALLY seems like a time for stackable headers!".
And I'd say : "You're right, but I didn't!".
I measure out how many pins are needed off the Arduino, then gently snap off that many with a pair of pliers.
*double check that the shield has the same number, as sometimes they have fewer.
To make soldering easier, placed the pins in a breadboard to hold them steady.
Gang's all here. Now to start on the software & cross device wiring harness.
Aiming to wrap this all up for a spooky Halloween build.
