RTC Alarm
Imagine you have an alarm clock that you set to wake up at a certain time. This is similar to an RTC alarm. RTC stands for Real Time Clock, which keeps track of time like a regular clock. An RTC alarm allows you to set a time when something needs to happen, just like your alarm clock wakes you up in the morning.
An RTC alarm works like this - You need to tell the device what time you want it to do something, and it will wake up and do it at that time. For example, you can use an RTC alarm to turn on or off the lights in your home, or to remind you to take medicine at a specific time.
To set an RTC alarm, you need to tell it what time you want it to go off. This is done by setting the hours, minutes, and seconds of the alarm. Once you set the alarm, it will go off at that time regardless of whether the device is on or off.
Overall, an RTC alarm is like a special clock that allows you to program it to do something at a certain time, just like setting an alarm clock to wake up in the morning.
