🎨 解决Leap Motion与Arduino数据交换问题：从报错到成功 🚀

我想做一个用Leap Motion感应手的位置再控制Aduino的舵机旋转做一些事情中间的数据交换用的是processing

但是现在出了一些问题
Aduino的代码已经准备好了
[mw_shl_code=csharp,true]#include <Servo.h>

Servo leapservo;
Servo leapservo2;
int servopin=6;
int servo2pin=10;
int breadboardledpin = 4;

void setup(){

  Serial.begin(9600);
  leapservo2.attach(servo2pin);
  leapservo.attach(servopin);
  pinMode(breadboardledpin,OUTPUT);
}

void loop(){
  if(Serial.available()){
char buffer[3];
Serial.readBytes(buffer,3);

int leaphandx = buffer[0];
if (leaphandx<=-76 && leaphandx >-128){
   leaphandx = 256-abs(leaphandx);
}
else if (leaphandx > -76 && leaphandx<0){
   leaphandx = 179;
}
else{
   leaphandx = buffer[0];
}

int leaphandy = buffer[1];
if (leaphandy<=-76 && leaphandy >-128){
   leaphandy = 256-abs(buffer[0]);
}
else if (leaphandy > -70 && leaphandy<0){
   leaphandy = 179;
}
else{
   leaphandy = buffer[1];
}

int breadboardled = buffer[2];
if(breadboardled>=0 && breadboardled<110){
   digitalWrite(breadboardledpin,HIGH);
}
else{
   digitalWrite(breadboardledpin,LOW);
}

leapservo2.write(leaphandx);
leapservo.write(leaphandy);

  }
  Serial.flush();
}[/mw_shl_code]

Processing的代码也准备好了
但是问题就在这里。。。。。。
