There is no other way to learn something than to implement it practically. So we are here with another interesting project on python.<\/p>\n

This time, you will learn how to create a simple alarm clock with python and Tkinter.<\/p>\n

Python alarm clock is a gui application, which can be used on a computer to set an alarm. Although it’s a simple project for beginners, but it’s interesting to implement various functionalities.<\/p>\n

Prerequisites<\/h3>\n

The prerequisites are: basic concepts of Python and Tkinter<\/p>\n

To install the libraries, you can use pip installer from the cmd\/Terminal:<\/p>\n

pip install tkinter\r\n<\/pre>\n
Download Python Alarm Clock Code<\/h3>\n
Before proceeding ahead, please download source code of python alarm clock: Python Alarm Clock Code<\/strong><\/a><\/p>\n

Functions Used<\/h4>\n
1. Setalarm:<\/strong> It sets an alarm by calling alarmClock method by passing the alarm time as argument(if the user has entered a correct and non-empty time).<\/p>\n
2. alarmclock:<\/strong> This is the most important method because it performs the following tasks:<\/p>\n
a. It stores the current time in time_now in specified format (“%H:%M:%S”)<\/p>\n
b. It also checks if current time matches the alarm time. As soon as time matches it displays a wake-up message and plays the alarm song using pygame and mixer. And if doesn\u2019t match the time_now it continues step b after sleeping for one second.<\/p>\n
Variables Used:<\/h4>\n
1. root: the main GUI window.<\/p>\n
2. Hrs, Mins, Secs: They are tkinter string variables that store the hour\u2019s, minute\u2019s and second\u2019s value entered by the user before setting an alarm.<\/p>\n
3. Greet: It is a label to display the message\u201d Take a short nap!\u201d.<\/p>\n
4. We also have hrbtn, minbtn , secbtn to take respective values from the user.<\/p>\n
