Hello everyone, i want to ask for your support and ideas.
By no means i am an expert in electronics, but i have a projet in mind an i would like to ask for your advice, please, i am looking the simplest way to solve it, and then see how should i continue.
i want to drive 45 rgb leds with an arduino, í´ve read about multiplexing, PWM , and that might be the solution, but it is late, i´m tired and i am looking some help from you guys-
The thing is as follows.
-i have a touch screen with different colors on it, maybe 2000, but the similar tones can be considered as one, reducing the usable colors at probably 200
-In the initial state, let´s say we are in the "red" color
-if a user touches the "blue" color on the screen, the fading time from "red" to "blue" is ten minutes.
-if another user touches the "orange" on the screen, the fading time from "blue" to "orange" is ten minutes again, an so on...
What components should i use to do this? it is just a project that i would like to know how it is done. Any advice will be great, explaining with simple words and maybe an example or a link.
