    Hey Guys,
    Recently i have decided to build a machine which will determine colors.
    For example i'll put in front the sensor a red circle and it will realize it's a red color.
    My question is where can i find good resources to start designing my project, and searching for materials to start building.
    I'll need to learn about the color and the electronic parts working with it.
    If you can provide me this information or give me a directions it will be awesome.

    I suggest you google "color sensor IC" as a start.

    Just checking - you are aware that there are many commercial products that do exactly this? Why build something that you can buy so easily?

    Hello,

    You could have a look at the following sensors.

    For a down-to-basics approach you could spin a RGB colour-filter wheel in front of a single photocell and compare the cell outputs for the three colour filters.

    A simpler way is to use red, green, and blue LEDs to illuminate the object, one colour at a time. Then you do not need coloured filters at the sensor.
