App Inventor通过蓝牙控制Arduino RGB LED灯依次点亮
使用蓝牙模块HC-05与App Inventor通信。早期的帖子因为要给MIT写博客，所以app的界面及编程环境用的是英文。（请忽略俺凌乱的接线）Arduino编程部分：
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);//SERIAL_8E2
Serial.setTimeout(3000);
pinMode(13, OUTPUT);
digitalWrite(13, HIGH);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
byte cmmd;
int insize;
while(1){
if((insize = Serial.available())> 0){
for(int i = 0; i < insize; i++){
cmmd = Serial.read();
}
}
switch(cmmd){
case 97:
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7, LOW);
break;
case 98:
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7, HIGH);
break;
case 99:
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
digitalWrite(7, LOW);
break;
case 100:
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
digitalWrite(7, HIGH);
break;
case 101:
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(7, LOW);
break;
case 102:
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(7, HIGH);
break;
case 103:
digitalWrite(5, HIGH);
digitalWrite(6, HIGH);
digitalWrite(7, LOW);
break;
case 104:
digitalWrite(5, HIGH);
digitalWrite(6, HIGH);
digitalWrite(7, HIGH);
break;
}
}
}

不错！ {:5_190:} 这个小白看起来很牛
