 Functional Overview

Timing: 3-15 minutes, two buttons control ("+", "-"), it can be controlled cyclically, that is, when "+" reaches 15 minutes, press "+" again to jump to 3; "-" to 3. Press "-" again to jump to 15.

* The sound alarm adopts a buzzer, and the sound frequency should be softer.

l Alarm time limit, automatically stop buzzing after 15 seconds

* The button must have a buzzer prompt (the button has a sound)
