Now I will explain how to make an arduino .ino code with an RGB that changes color depending on the light. Everything starts by declaring the variables, that is, the different LED colors, the sensor and the port. Then comes the setup void where we declare the settings of how the code works, for example we declare that it is analog. Finally, the void Loop comes, where we declare to what intensities the LED will light up and in what color it will do it, apart from marking the way it is connected.
