Arduino向Unity传数据
Arduino程序int x=0;int y=0;
int b=0;
bool l=false;//按钮状态
void setup() {
pinMode(2, INPUT);
pinMode(13, OUTPUT);
Serial.begin(9600);
}
// the loop function runs over and over again forever
void loop() {
l=digitalRead(2);
if(l){digitalWrite(13,LOW);b=0;}
else{digitalWrite(13,HIGH);b=1;}
x=analogRead(1);
y=analogRead(2);
Serial.print("*");
Serial.print(x);
Serial.print(",");
Serial.print(y);
Serial.print(",");
Serial.print(b);
Serial.print("#");
delay(2);
}

此版本不易死机。 你好，想问一下有Arduino与unity交互，通讯的教程网站或资料嘛 Dreams 发表于 2019-11-9 21:30

ardunio 和 unity交互实际上就是互传字符串，可以分别学下字符串处理的例子。使用的时候要考虑ardunio的速度限制，字符串不能太长。
