Arduino Wave Generator Tank
Welcome me matey to Davy Jones' miniature locker. To analyze yer wave and buoyancy mechanics while we plunder wenches, drink Rum and supplement with vitamin C, we rigged an Arduino Micro, (2) servos and potentiometer with if and for codes to generate various wave frequencies upon the sovereign seas (in a small acrylic case cast from a picture frame). Arrr--gh!


Ingredients
Arduino Nano

10K Potentiometer
