Arduino 实验 —— 红外遥控RGB灯

学会使用遥控器进行控制RGB灯

• Arduion主板
• 红外接收器
• RGB灯
• 遥控器
• 杜邦线
• USB数据线

Arduino IDE

1、建立电路

2、烧录代码

#include<IRremote.h> const int irReceiverPin = 7; const int rPin = 9; const int gPin = 10; const int bPin = 6; int r; int b; int g; IRrecv irrecv(irReceiverPin); decode_results results; void setup() { 
           pinMode(rPin, OUTPUT);   pinMode(gPin, OUTPUT);   pinMode(bPin, OUTPUT);   Serial.begin(9600);   irrecv.enableIRIn(); }  void loop() { 
           if (irrecv.decode(&results))   { 
             Serial.print(span class="token string">"irCode:");
    Serial.print(results.value, HEX);
    Serial.print(",bits:");
    irrecv.resume();
  }
  delay(300);
  if (results.value)
  { 
        
    if (results.value == 0xFFE21D)
    { 
        
      r = 128;
      analogWrite(rPin, g);
    }
    if (results.value == 0xFFC23D)
    { 
        
      g = 128;
      analogWrite(gPin, g);
    }
    if (results.value == 0xFF906F)
    { 
        
      b = 128;
      analogWrite(bPin, b);
    }
  }

  if (results.value == 0xFF6897)
  { 
        
    analogWrite(rPin, 0);
    analogWrite(gPin, 0);
    analogWrite(bPin, 0);
  }
}

遥控器按CH+键一次显示红灯再按一次关闭，按▷║键一次显示绿灯再按一次关闭，按EQ键显示蓝灯再按一次关闭，按0键关闭灯光。
