ContentsObjectiveHere we adopt a color sensor to read color value from a object around you and the LED light on the sensor will turn to the corresponding color as the object.  PrincipleThe color sensor can read color values and then be analyzed by CoreUSB to get the light to show the corresponding color.  Equipment

 LED light's connection method can refer to the picture above. Please mind the connection order, which starts from LED's IN interface to OUT. 
 In bad light, you can turn off LED light on the color sensor. Get the dice in the middle of the color sensor close to any object with different color and the led light will change accordingly.  Reference color:  ResultYou can DIY your LEGO chameleon. Just put the color sensor close the object and the color of the LED light will change to the same as the object.  Video |
