在Java中阅读Arduino A0，A1和A2，独立

Question

我从控制台上得到它：

0

====数据完成====

3

====数据完成====

5

====数据完成====

我想达到彼此分开的A0，A1，A2的值，但它们都在一起。 我的arduino代码是：

int firstSensor = 0; // first analog sensor
int secondSensor = 0; // second analog sensor
int thirdSensor = 0; // third analog sensor
int inByte = 0;   // incoming serial byte

void setup() {
  Serial.begin(9600);
}

void loop() {
  // read first analog input
  firstSensor = analogRead(A0);
  // delay 10ms to let the ADC recover:
  delay(10);
  // read second analog input
  secondSensor = analogRead(A1);
  delay(10),
  // read third analog input
  thirdSensor = analogRead(A2);
  // send sensor values:
 Serial.println(firstSensor);
 Serial.println(secondSensor);
 Serial.println(thirdSensor); 
}

我是Java，Arduino和这里的新手

提前感谢

查看这一点 简而言之，您需要添加一些额外的数据，例如

<sensor_name>=<sensor_value>然后在您的Java代码中，您可以在=上拆分并获取传感器名称和值
