2、e(BluePin,OUTPUT);}voidloop(){if(Serial.available()>0){intindex=0;delay(100);intnumChar=Serial.available();if(numChar>15){numChar=15;}while(numChar--){buffer[index++]=Serial.read();}splitString(buffer);}}voidsplitString(char*data){Serial.print("Dataentered:");
3、Serial.println(data);char*parameter;parameter=strtok(data,",");while(parameter!=NULL){setLED(parameter);parameter=strtok(NULL,",");}for(intx=0;x<16;x++){buffer[x]=' ';}Serial.flush();}voidsetLED(char*data){if((data[0]=='r')

11、(data[0]=='B')){intAns=strtol(data+1,NULL,10);Ans=constrain(Ans,0,255);analogWrite(BluePin,Ans);Serial.print("Blueissetto:");Serial.println(Ans);}}3程序截图：设置:黄灯亮度1，红灯亮度50，绿灯亮度100，输入：r1b50g100
可以观察到。绿灯最亮，红灯次之，黄灯最暗4动态效果：见视频：2数
12、码管骰子1功能介绍：当按下一个按钮时候，数码管数字渐变，频率由快而慢，并最后随机的停在一个数字上。2程序代码：voidclearNum(){for(inti=4;i<=10;i++){digitalWrite(i,LOW);}}voidshowNum1(){clearNum();digitalWrite(9,HIGH);digitalWrite(10,HIGH);}voidshowNum2(){clearNum();digitalWrite(5,HIGH);digitalWrite(6,HIGH);digitalW
