Imagine a clock as a sleepy friend who wakes up at the same time every day. Inside it, there's something called a timer that tells it when to ring. This timer is like a little counting machine, once it reaches the right number, it makes the bell go ding! Just like how your alarm knows when to wake you up.
Examples
- Your grandfather clock rings every hour because it counts down from 60 seconds and then hits the bell.
- A digital clock with an alarm knows when to ring because it’s counting minutes until your wake-up time.
- Even a smart watch can tell you when to ring your phone by using vibrations and sensors.
