Ok so like the title says I have an old evo 4G and started thinking... maybe there's a way to make it into a controller of some kind. I figured the screen can dim so maybe I could make it into a controller to dim my maxwellen drivers on my tank. I've heard these are and they aren't dimable but I am able to manually dim them with a potentiometer. Does anyone know if anything of the like is doable? Or even a fun project to do with an old smart phone. Please forgive my ignorance to the arduino world, please use small words lol, and mods feel free to move if this is better suited for a different section.
