I have no idea why, but having wracked my brain all day and trying google guesses, I cant find or remember what this device is.
You know the things that tell you what colour something is? they are used for say when you take an object in to a paint shop and they use this sensor to get the colour so they can make the paint up. The one I used to have and the one I want, was/might still be sold by spark fun. it was a sensor and told you what colour light was pointing at it.
I kid you not, even now i cant get remotely close to what they are called!! I have a complete mental block on what they call them! I know its dead simple and I can even picture it in my mind, but i cant even think of what to google for!! Hopefully someone can get what I am on about from the description!! Its awful, its like forgetting what a pencil is called and barely being able to describe what it does!!
I need to look at a data sheet for one and possibly get one of these things again. oh and light thingy in google dosnt bring it up!
