Arduino Color Mixer

This tutorial is pretty simple and needs a bit Arduino and natural philosophy data, if you are not conversant in Arduino, I will embrace links to guide you thru the tutorial.

In this tutorial, we’ll generate all the doable colors that you simply} will see with just a twist. it’ll conjointly cause you to see through the RGB color model and understanding however today’s displays work.

We’ll conjointly use Arduino analog Input / Output ( noted as I/O later in the tutorial ) and can learn the way to browse and write analog voltages on Arduino pins.

This is my initial trial of the circuit ( a jiffy past, it had a little downside whereas increasing the pot worth, however, I fastened it later. )
