Question

我尝试从 Arduino 向我的 ESP 控制器发送一个值，但我没有成功读取消息... 我总是只得到一些数字。我需要在未来发送多个读数的多个值...

Arduino 代码：

    int analogPin = A0;
int val = 0;
void setup(){
Serial.begin(115200);
delay(2000);
}
void loop()
{
  Serial.print('Value is: ');
if (Serial.available()) {  
   val = analogRead(analogPin);
   Serial.println(val);
  }
delay(1000);
}

ESP 代码：[在此处输入图片描述][1]

String incomingByte ;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
}

void loop() {
  // send data only when you receive data:
  if (Serial.available() > 0) {
    // read the incoming byte:
    incomingByte =  Serial.readStringUntil('\n');

    // say what you got:
    Serial.print("I received: ");
    Serial.print(incomingByte);
  }
}
```

ANy Idea how to solve this?

Arduino Uno 和 ESP 串行通信无法接收消息
