SimpleAlarm

Simple Alarm object that extends SimpleTime and adds alarm-like features. Tested on ESP32 . Adds alarm trigger and persistent alarm state between power cycles

Dependencies: Requires the Preferences Library for storing persistent alarm state between shutdowns, https://github.com/espressif/arduino-esp32/blob/master/libraries/Preferences/examples/StartCounter/StartCounter.ino

Example with NTPClient:

void setup()
{
  /* your other setup here */

  NTPClient timeClient(ntpUDP, "au.pool.ntp.org", 39600, 60000);
  SimpleAlarm simpleAlarm = SimpleAlarm();

  simpleAlarm.set(8,30,0);  // set alarm to 8:30am
  simpleAlarm.save();  // save alarm to memory
  simpleAlarm.load(); // load alarm from memory
  simpleAlarm.enable();  // enable alarm
}

void loop()
{
  /* your other loop here */

  timeClient.update();
  SimpleTime time(timeClient.getHours(), timeClient.getMinutes(), timeClient.getSeconds());

  if(simpleAlarm.check(time))
  {
    // Alarm activated
  }
}

Example with callbacks

void alarm()
{
    // Alarm Activated callback function
}

void setup()
{
  /* your other setup here */

  NTPClient timeClient(ntpUDP, "au.pool.ntp.org", 39600, 60000);
  SimpleAlarm simpleAlarm = SimpleAlarm();

  simpleAlarm.setCallBack(alarm);
  simpleAlarm.set(8,30,0);  // set alarm to 8:30am
  simpleAlarm.enable();  // enable alarm
}

void loop()
{
  /* your other loop here */

  timeClient.update();
  SimpleTime time(timeClient.getHours(), timeClient.getMinutes(), timeClient.getSeconds());
  simpleAlarm.check(time));
}
