Detecting colors with LDR and Arduino
In this tutorial we are going to see how it is possible to detect colors with LDR and a simple RGB led.
the principle behind it is that each object in a given color that you see, reflects light differently when you light on it with the basic RGB colors in a cycle.
the value that is the lowest is the closest color of the object.
on my next video i assume i'll do something in python that shows a color .
