- Wed Dec 14, 2022 9:20 pm #95633 My NTP Clock project will be doing different things while displaying time, one task is to run code at a certain time. My full code at bottom. My displayed time is formatted like this "TIME:00:00:00", so I tried to use:

Code: Select allif (Time == "TIME:19:52:00") {
      Serial.println("Timer Event Activated !!");  //No output
    } 

This code failed, with no serial output. It was a variable type mismatch. I converted the Time array to a String, the time comparison then worked.

Code: Select allvoid loop() {

  timeClient.update();
  unsigned long unix_epoch = timeClient.getEpochTime();    // Get Unix epoch time from the NTP server

  second_ = second(unix_epoch);
  if (last_second != second_) {

    minute_ = minute(unix_epoch);
    hour_   = hour(unix_epoch);
    day_    = day(unix_epoch);
    month_  = month(unix_epoch);
    year_   = year(unix_epoch);

    Time[12] = second_ % 10 + 48;
    Time[11] = second_ / 10 + 48;
    Time[9]  = minute_ % 10 + 48;
    Time[8]  = minute_ / 10 + 48;
    Time[6]  = hour_   % 10 + 48;
    Time[5]  = hour_   / 10 + 48;

    Date[5]  = month_  / 10 + 48;
    Date[6]  = month_  % 10 + 48;   
    Date[8]  = day_   / 10 + 48;
    Date[9]  = day_   % 10 + 48;
    Date[13] = (year_   / 10) % 10 + 48;
    Date[14] = year_   % 10 % 10 + 48;

    // Send time and date to serial monitor
    Serial.println(Time);
    Serial.println(Date);
   
//----------------------- Timed Event ---------------------------------
   String strTime = String(Time);
    if (strTime == "TIME:21:19:00") {
      Serial.println("Timer Event Activated !!");
    } 

    // Display time and date on the 16x2 LCD
    lcd.setCursor(0, 0);
    lcd.print(Time);
    lcd.setCursor(0, 1);
    lcd.print(Date);
    last_second = second_;
   }
  delay(200);
}

Please excuse this post as I resolved it.
But this seems to be an easy way to convert a simple clock to a multi-function project that can do timed events, with no sleep requirement.
