I have the following code:

//check if current minute is less than 10. (0,1,2,3 etc)
if (input < 10) {
//add 0 to beginning of the string version of current minute (00, 01, 02, 03 etc)
minutes = "0" + String(input);

}

void setup() {
// put your setup code here, to run once:
lcd.begin(16, 2);
SwSerial.begin(9600);
Serial.begin(9600);
Blynk.begin(Serial, auth);
setSyncInterval(10);
timer.setInterval(5000L, clockDisplay);
pinMode(7, INPUT);
}
void loop() {
// put your main code here, to run repeatedly:
Blynk.run();
timer.run();
alarmTimer.run();
}
And I’m trying to make it so that when the time fetched from TimeLib/WidgetRTC is the same as the time stored after using the TimeInputWidget are the same, the device will display the alarm clock time.
The functions of note are:
isAlarmReached() is a boolean that returns whether the current time is equivalent to the stored time.
BLYNK_WRITE(V1) stores the time that the user inputs.
alarmDisplay() displays the set message and will also do some other stuff, basically needs to be called when the alarm time is reached.
clockDisplay() displays the time normally, but can be interrupted by the alarm setting confirmation screen and the alarm reached screen.
But as it stands right now, when the time I entered is reached, the device behaves as if nothing happened. When I enter my alarm time it works, interrupts the clock etc, but when it reaches the time I set it just ignores it. Any help?
