Arduino IDE为以下代码提供错误

代码可以编译，但不能上传。 代码是：

int fsrPin = 0;     // the FSR and 10K pulldown are connected to a0
int fsrReading;     // the analog reading from the FSR resistor divider
 
void setup(void) {
  Serial.begin(115200);   
}
 
void loop(void) {
  fsrReading = analogRead(fsrPin);  
 
  Serial.print("Analog reading = ");
  Serial.print(fsrReading);     // print the raw analog reading
 
  if (fsrReading < 10) {
    Serial.println(" - No pressure");
  } else if (fsrReading < 200) {
    Serial.println(" - Light touch");
  } else if (fsrReading < 500) {
    Serial.println(" - Light squeeze");
  } else if (fsrReading < 800) {
    Serial.println(" - Medium squeeze");
  } else {
    Serial.println(" - Big squeeze");
  }
  delay(1000);
}

我已经检查了所有的端口和代码，一切似乎都很好，但是avr dude错误不断出现

看起来USB电缆和Arduino的连接有些松动。您可以按照以下几个步骤进行计数：

尝试重新连接USB电缆

重新启动ArduinoIDE

重启电脑

你的问题应该解决
