Question

我一直在编写一个程序，要求我从Arduino的串行监视器中获取输入。但是我遇到了一些问题。这是我的代码。更新：这是我在几次修订后创建的新代码。

//This next line is the line that was highlighted
read.Serial(searchedItem);

void setup() {
//setup code here, to run once:
Serial.begin(9600);
}

void loop() {
//loop code here, to run forever:
if (Serial.available() > 0) {
  // read the incoming byte:
  searchedItem = Serial.read();
  //Code here
  if (searchedItem == "Red LED", "red led", "Red led") {
    searchedItem = Red_LED;
    if (searchedItem => 1) {
     Serial.println("\nFound!\nYou have ", Red_LED, "Red LEDs");
      }
    }
  }
}

Answer 1

您的代码不在函数中。你不能这样做，这就是为什么这条线被“突出显示”。

Answer 2

此代码不在任何函数内：

read.Serial(searchedItem);

此外，该函数为Serial.read。您需要确保缓冲区中有可用数据Serial.available() 在loop()内尝试类似的内容：

if (Serial.available() > 0) {
    // read the incoming byte:
    incomingByte = Serial.read();
    //Your code here
}
