1、硬件部分

通过三个电位器来任意变换对应的R、G、B，组合成任何你想要的颜色，在家做个心情灯吧，随心情任意切换。至此就是一些组合，不再详述，仅为做笔记用。

2、代码部分

//LED三个灯脚输出
int red = 9;
int blue = 10;
int green = 11;
//电位器三个模拟输入
int potRed = 0;
int potBlue = 1;
int potGreen = 2;

void setup() {
  pinMode(red,OUTPUT);
  pinMode(blue,OUTPUT);
  pinMode(green,OUTPUT);
  Serial.begin(9600);
}

void loop() {
  int valRed = map(analogRead(potRed),0,1023,0,255);
  int valBlue = map(analogRead(potBlue),0,1023,0,255);
  int valGreen = map(analogRead(potGreen),0,1023,0,255);

  Serial.print("Red:");
  Serial.print(valRed);
  Serial.print("  Green:");
  Serial.print(valGreen);
  Serial.print("  Blue:");
  Serial.println(valBlue);
  
  colorRGB(valRed,valGreen,valBlue);
}

void colorRGB(int iRed,int iGreen,int iBlue){
  analogWrite(red,constrain(iRed,0,255));
  analogWrite(blue,constrain(iBlue,0,255));
  analogWrite(green,constrain(iGreen,0,255));
}
