距離感測器和TM1637七段顯示器整合問題

shsps940316

目前想要做用距離感測器
然後把數據顯示在七段顯示器上面
一直卡在Arduino開發板編譯錯誤
希望各位大大幫忙看是哪裡寫錯

(設這是原始檔)
#include <Arduino.h>
#include <TM1637Display.h>

#define DIO 3 // connect DIO to pin 3

TM1637Display display( CLK, DIO );

void loop() {
  
sensorValue = analogRead(0);   
if(sensorValue>=280&&sensorValue<=620) // If sensorValue between 280 ~ 620 ,will be touch off
{
   distance = 28250 / ( sensorValue - 229.5 );
   long int averaging = 0;
   //儲存10次距離數據
   for(int i = 0 ; i<2 ; i++ ) //sampimg 10 time within 1 seconds
   {
    averaging = averaging + distance;
    delay(100);
   }
   //得到距離數據之平均值
   distance = averaging / 2;
  Serial.print("Distance: ");
  display.setSegments(blank);
  int dis = distance();
  display.showNumberDec(dis , false , 3 , 1);
  Serial.print(distance);
  Serial.println("cm");

   averaging = 0;
  //重置紅外線感測器之數值為0
  delay(1500);
  //Wait another 1.5 second for the next read
  //延遲1.5秒
}
  delay(500);  //Wait another 1/2 second for the next read
