Modeling and Designing of Color Detector using Arduino

The utility model discloses a colour detector and a colour recognition device, wherein the colour detector comprises a luminous source which emits detecting light to to-be measured objects, and a sensor which is used for receiving reflected light to measuring color information, wherein the colour recognition device comprises the color detector, a data processing unit which is used for recognizing colour through collecting data, storing data and comparing data and is used for judging relative cases, and an output unit used for outputting color recognition results. The colour detector and the colour recognition device can be applied in electronic whiteboards, when writing on the whiteboards, the detector and the device can automatically recognize the colour of a writing pen, which is convenient for writers as writing on common blackboards or whiteboards, and the color of the handwritings depends on the color of writing pens.The colour detector and the color recognition device are also can be applied to other situations which need to recognize colors. For the colour recognition we refer to the basic rgb pattern or the hue or colour circle
