Outline
PrincipleMobile clients can simulate the color of the lights via three progress indicators which send the quantitative values obtained from simulation experiment to Microduino Core via BT. Thus, we can easily control the color of RGB lights by calculating since we get both the simulated values and using function analogWrite(). In order to have a better control experience, we need to connect pins of RGB lights to those of PMW（3、5、6、11) . Since both Microduino BT and Microduino Core adopt soft serial port for communication, we can't connect RGB lights to pins (9,10). Otherwise, data chaos may appear. Bill of Materials
