Magical Colour Copying Chameleon Lamp
fjordcarver Dad, maker, dreamer, hacker, painter.
In this Instructable, I will show you how to make an Arduino powered lamp that detects the colour under it and then attempts to emulate that colour. All using easy to find parts (most can be found in the Dollar store with the exception of the Arduino of course).
It turns out that a colour detection module can be built for next to nothing, and the results are astoundingly good for the investment.
The biggest hurtle in this project is getting the balance right on our sensor as we are using LEDs to represent the colour being detected, which becomes our limit. Dark colours are more difficult to represent. The sensor still does a good job at detecting and giving a reliable reading, but again, balancing becomes the real issue. Reflectivity will also play with the readings. That being said, this sensor would work great for all manner of colour detecting projects. Best of all it is super cheap to make.
I really hope that a few of you out there both copy and improve on my lamp, or find some other great uses for this cheap, easy to make, Arduino friendly Colour sensor.

Using an RGB LED to Detect Colours
Dad, maker, dreamer, hacker, painter.
I am going to show you how you can use an RGB LED and a Cds photocell as a colour sensor for a micro-controller. I will illustrate the method to retrieve a colour using Arduino, and I will show you a how you can verify the colour being scanned with a small Processing sketch.
We will be making this colour sensor on a breadboard, but it is easily transferred onto a prototyping board, and for those who fab their own boards, this would be an awesome kit that is super cheap to throw together. I am sure it would only take about two minutes to write a gerber file for this circuit and make a nice little finished sensor.

Pretty cool and looks easy enough to do too:)
