我正在开发推特心情灯并拥有arduino和python代码。丢失所有我的python代码后，它不得不从内存重制它，但我遇到了一些问题。 python代码将rgb数据发送到arduino以更改rgb led的颜色。出于某种原因，arduino没有拿起最后一个值，并且正在将第二个值更改为蓝色led。
例如：我发送了50,50,50，这是一个暗淡的白色，led显示紫色（蓝色和红色），如果我发送0,0,255（蓝色），它保持空白，如果我发送0,255,0 （绿色）它显示蓝色。
我不知道已经尝试过这么多东西才能让它发挥作用。
Python代码： 我知道我发送数据两次是发送功能工作的唯一方式

Arduino代码：

void setup() {
// put your setup code here, to run once:
pinMode(Red,OUTPUT);
pinMode(Blue,OUTPUT);
pinMode(Green,OUTPUT);
Serial.begin(9600);
analogWrite(Red,0);
analogWrite(Blue,0);
analogWrite(Green,0);
}
void loop() {
// put your main code here, to run repeatedly:
if (Serial.available() > 0){
String string = Serial.readStringUntil('\n');
int comma1 = string.indexOf(',');
int comma2 = string.indexOf(',');
int none = string.indexOf('\n');
String first = string.substring(0,comma1);
String second = string.substring(comma1 + 1,comma2);
String third = string.substring(comma2 + 1, none);
int r = first.toInt();
int g = second.toInt();
int b = third.toInt();
Serial.print(string);
analogWrite(Red,r);
analogWrite(Green,g);
analogWrite(Blue,b);
}
}
所有这些代码都是从其他代码编辑或基于它编写的，因此有一些注释对python程序没有任何意义 此外，我需要这个项目由arduino日（4月1日）完成 非常感谢你提前

愚蠢的错误。我的第二个逗号索引正好是arduino代码中第一个（oops）的位置
