Question

我正在用rgb制作arduino控制的灯。我正在尝试在每种颜色之间增加平滑的过渡，这会从led发光。我不希望单独对频道进行动画处理。目前，它一次只能使用一个通道，而晶体管只能在亮度增加时使用。

    const int redpin = 9;
    const int greenpin = 10;
    const int bluepin = 11;
    int currRed = 0;
    int currGreen = 0;
    int currBlue = 0;
    int dur = 1000;

    void setup() {
      pinMode(redpin, OUTPUT);
      pinMode(greenpin, OUTPUT);
      pinMode(bluepin, OUTPUT);
      Serial.begin(9600);
    }

    void loop() {
      if (Serial.available()) {
      int red = Serial.parseInt();
      int green = Serial.parseInt();
      int blue = Serial.parseInt();

      if (Serial.read() == '\n') {
        red = constrain(red, 0, 255);
        green = constrain(green, 0, 255);
        blue = constrain(blue, 0, 255);
        }

      updateRGBfade(redpin, red, dur, currRed);
      updateRGBfade(greenpin, green, dur, currGreen);
      updateRGBfade(bluepin, blue, dur, currBlue);
      }
    }



   void updateRGBfade(int pin, int col, int animdur, int currcol) {
      if (col > currcol) {
        for (int setto = currcol; setto < col; setto++) {
          analogWrite(pin, setto);
          delay(5);
        }
      }
      if (col < currcol) {
        for (int setto = currcol; setto > col; setto=setto-1) {
          analogWrite(pin, setto);
          delay(5);
        }
      }
    }

Currcolors（currRed，currGreen和currBlue）被视为恒定且等于零。因此，updateRGBfade函数仅在发生阻塞时才首先运行，因为currcol始终为零，我认为col通常大于零。因此该功能仅运行增加过程。如果阻止波纹管延迟（5）s

，则可以在函数中添加跟随行

if(pin == redpin){
currRed = currcol;
}else if(pin == greenpin){
currGreen = currcol;
}else if(pin == bluepin ){
currBlue = currcol;
}

对不起，我的英语不好。
