第一次玩ds3231,想做时控灯，为什么不定时开灯呢

#include <DS3231.h>
// Init the DS3231 using the hardware interface
DS3231  rtc(SDA, SCL);
void setup()
{
  // Setup Serial connection
  Serial.begin(115200);
  // Uncomment the next line if you are using an Arduino Leonardo
  //while (!Serial) {}
  
  // Initialize the rtc object
  rtc.begin();
  
  // The following lines can be uncommented to set the date and time
// rtc.setDOW(SATURDAY);     // Set Day-of-Week to SUNDAY
rtc.setTime(17,8,00);     // Set the time to 12:00:00 (24hr format)
//rtc.setDate(30,5,2020);   // Set the date to January 1st, 2014
}

void loop()
{
  int aa=13;
  
  if (rtc.getTimeStr()=="17:10:00")
{
  digitalWrite(13,HIGH);
  delay(100);
}
  // Send Day-of-Week
  Serial.print(rtc.getDOWStr());
  Serial.print(" ");
  
  // Send date
  Serial.print(rtc.getDateStr());
  Serial.print(" -- ");

  // Send time
  Serial.println(rtc.getTimeStr());
  
  // Wait one second before repeating
  delay (1000);


}

大神们，帮我看看看吧

你应该看看你的时间走到哪里了！应该弄个串口打印之类的，看你的程序如果中间重新上电，时间会从0点重新走时。时间设定不能每次上电都无条件执行。最好弄个串口设定时间。
