Before proceeding ahead, please download source code of python alarm clock: Python Alarm Clock Code


from time import strftime 
from tkinter import * 

import time
import datetime
from pygame import mixer
root = Tk() 
root.title('TechVidvan Alarm-Clock') 

def setalarm():

def alarmclock(alarmtime): 
    while True:
        if time_now==alarmtime:
            Wakeup=Label(root, font = ('arial', 20, 'bold'),
            text="Wake up!Wake up!Wake up",bg="DodgerBlue2",fg="white").grid(row=6,columnspan=3)
            print("wake up!")


greet=Label(root, font = ('arial', 20, 'bold'),
text="Take a short nap!").grid(row=1,columnspan=3)

hrbtn=Entry(root,textvariable=hrs,width=5,font =('arial', 20, 'bold'))

width=5,font = ('arial', 20, 'bold')).grid(row=2,column=2)

width=5,font = ('arial', 20, 'bold')).grid(row=2,column=3)

setbtn=Button(root,text="set alarm",command=setalarm,bg="DodgerBlue2",
fg="white",font = ('arial', 20, 'bold')).grid(row=4,columnspan=3)

timeleft = Label(root,font=('arial', 20, 'bold')) 

Functions Used

1. Setalarm: 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).

2. alarmclock: This is the most important method because it performs the following tasks:

a. It stores the current time in time_now in specified format (“%H:%M:%S”)

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’t match the time_now it continues step b after sleeping for one second.

Variables Used:

1. root: the main GUI window.

2. Hrs, Mins, Secs: They are tkinter string variables that store the hour’s, minute’s and second’s value entered by the user before setting an alarm.

3. Greet: It is a label to display the message” Take a short nap!”.

4. We also have hrbtn, minbtn , secbtn to take respective values from the user.
