Objective Use color sensor to read different color around you and the light will make change and turn to the corresponding color. 600px Principle The color sensor can read color values and then be analyzed by CoreUSB to get the light to show the corresponding color. 600px Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board Microduino-Color detector 1 Color sensor Microduino-Light 1 Light-sensitive sensor mCookie-OLED 1 Display module mCookie-BM 1 Battery management 600px Preparation Setup 1：Connect CoreUSB and PC/MAC with a USB cable, then open Arduino IDE. 600px Setup 2：Click Files > Examples > mCookie > _303_BashfulChameleon, then load the program. 600px Setup 3：Load the code, select the right board and COM port, and download the program. When you see "Done Uploading" notice, it means program has been written into CoreUSB. 600px Program Description Control pin description #define PIN 6 Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, PIN, NEO_GRB + NEO_KHZ800); Color matching redValue=map(red, 1024, 2048, 0, 255); greenValue=map(green, 1800, 2824, 0, 255); //blueValue=map(blue, 1024, 2048, 0, 255); blueValue=map(blue, 1024, 1792, 0, 255); Hardware Buildup Setup 1: Connect the color sensor to IIC of Sensorhub and LED light to D6. 600px 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. Setup 2: Connect the activated battery box to BM. Setup 3：Stack all modules together without fixed order and finish the circuit buildup. 600px 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. 600px Reference color: 参考颜色： 600px Result You 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. 600px Video
