Create an Alarm Clock using Tkinter

Prerequisite: Python GUI – tkinter, winsound, time, and datetime.

As we all know, nowadays wake up on time is a very difficult task. The solution is the Alarm Clock. In this article, we will learn, How to create an Alarm Clock using Tkinter in Python. Without alarms, several people would oversleep and land up late for work. Alarm clocks may also be useful for keeping sleep schedules regular.

• Tkinter: Python offers multiple choices for developing a GUI (Graphical User Interface). Out of all the GUI strategies, tkinter is that the most ordinarily used technique. It’s a customary Python interface to the Tk GUI toolkit shipped with Python.
• Winsound: The winsound module provides access to the essential sound-playing machinery provided by Windows platforms. It includes functions and a number of other constants. Beep the PC’s speaker.
• time: Time module in Python provides varied time-related functions. This module comes with Python’s normal modules.
• datetime: The main focus of datetime is to form it simpler to access attributes of the thing associated with dates, times, and time zones.

Below is what GUI looks like:-

Let’s Understand step by step implementation:

Step1: Import Required Library

Python3

# Import Required Library
from tkinter import *
import datetime
import time
import winsound

Step 2: Add Button, Labels, Frame, and option menus

Syntax:

# Button

Button(Object Name, text=”Enter Text”,**attr)

# Label

Label(Object Name, text=”Enter Text”, command=”Enter Command” , **attr)

# Frame

Frame(Object Name, **attr)

# Option Menu

OptionMenu(“Object Name”, “Data Type”, “list of value in form of tuple”, **attr)

We will create a three-option menu:-

• Hours (00–24)
• Minutes (00–60)
• Seconds (00–60)

Time is in 24-hour time format.

Step 3: Make a function named alarm(), which performs alarm clock work.

Python3

def alarm():
    # Infinite Loop
    while True:
        # Set Alarm
        set_alarm = f"{hour.get()}:{minute.get()}:{second.get()}"

        # Wait for one seconds
        time.sleep(1)

        # Get current time
        current_time = datetime.datetime.now().strftime("%H:%M:%S")

        # Check whether set alarm is equal to current time or not
        if current_time == set_alarm:
            print("Time to Wake up")
            # Playing sound
            winsound.PlaySound("sound.wav",winsound.SND_ASYNC)

Below is the full implementation:

• Make Infinite Loop
• Get hours, minutes, seconds value from the user
• Wait for one second using time module
• Get Current time using datetime module
• Check if the current time is equal to set time; play sound using winsound module

Python3

# Import Required Library
from tkinter import *
import datetime
import time
import winsound
from threading import *

# Create Object
root = Tk()

# Set geometry
root.geometry("400x200")

# Use Threading
def Threading():
    t1=Thread(target=alarm)
    t1.start()

def alarm():
    # Infinite Loop
    while True:
        # Set Alarm
        set_alarm_time = f"{hour.get()}:{minute.get()}:{second.get()}"

        # Wait for one seconds
        time.sleep(1)

        # Get current time
        current_time = datetime.datetime.now().strftime("%H:%M:%S")
        print(current_time,set_alarm_time)

        # Check whether set alarm is equal to current time or not
        if current_time == set_alarm_time:
            print("Time to Wake up")
            # Playing sound
            winsound.PlaySound("sound.wav",winsound.SND_ASYNC)

# Add Labels, Frame, Button, Optionmenus
Label(root,text="Alarm Clock",font=("Helvetica 20 bold"),fg="red").pack(pady=10)
Label(root,text="Set Time",font=("Helvetica 15 bold")).pack()

frame = Frame(root)
frame.pack()

hour = StringVar(root)
hours = ('00', '01', '02', '03', '04', '05', '06', '07',
         '08', '09', '10', '11', '12', '13', '14', '15',
         '16', '17', '18', '19', '20', '21', '22', '23', '24'
        )
hour.set(hours[0])

hrs = OptionMenu(frame, hour, *hours)
hrs.pack(side=LEFT)

minute = StringVar(root)
minutes = ('00', '01', '02', '03', '04', '05', '06', '07',
           '08', '09', '10', '11', '12', '13', '14', '15',
           '16', '17', '18', '19', '20', '21', '22', '23',
           '24', '25', '26', '27', '28', '29', '30', '31',
           '32', '33', '34', '35', '36', '37', '38', '39',
           '40', '41', '42', '43', '44', '45', '46', '47',
           '48', '49', '50', '51', '52', '53', '54', '55',
           '56', '57', '58', '59', '60')
minute.set(minutes[0])

mins = OptionMenu(frame, minute, *minutes)
mins.pack(side=LEFT)

second = StringVar(root)
seconds = ('00', '01', '02', '03', '04', '05', '06', '07',
           '08', '09', '10', '11', '12', '13', '14', '15',
           '16', '17', '18', '19', '20', '21', '22', '23',
           '24', '25', '26', '27', '28', '29', '30', '31',
           '32', '33', '34', '35', '36', '37', '38', '39',
           '40', '41', '42', '43', '44', '45', '46', '47',
           '48', '49', '50', '51', '52', '53', '54', '55',
           '56', '57', '58', '59', '60')
second.set(seconds[0])

secs = OptionMenu(frame, second, *seconds)
secs.pack(side=LEFT)

Button(root,text="Set Alarm",font=("Helvetica 15"),command=Threading).pack(pady=20)

# Execute Tkinter
root.mainloop()

Output:
