Turn your Raspberry Pi into an Azaan/Prayer clock


Recently I've been playing with the raspberry pi and given it's Ramadan, I thought I'd see if I could turn it into an Azaan (Islamic call to prayer) clock. Given the RPI is low powered I can leave it on and it doesn't need a monitor, keyboard, mouse, etc plugged in.

This is what I did:

1. Plug in a speaker into the 3.5mm audio output on the raspberry pi

2. Download python code from prayTimes.org to calculate prayer times

3. Download azaan mp3 from prayTimes.org again.

4. Write a python script to set jobs in crontab to play the azaan mp3 at the appropriate time (see code below or download here). The python code from prayTimes.org has to be in the same folder for this to work.

My script utilizes the python crontab library. More info on setting this up available on the links below

Python crontab: http://pypi.python.org/pypi/python-crontab/
Installing modules: http://docs.python.org/2/install/index.html

The bits you may need to configure yourself are:

a) Longitude and Latitude (currently set to London UK)
lat = 51.5171
long = 0.1062

b) Timezone (currently set to 0+GMT and daylight savings =1 )
times = PT.getTimes((now.year,now.month,now.day), (lat, long), 0,1) 

c) Location of azaan mp3:
strPlayAzaanMP3Command = 'omxplayer -o local /home/pi/Downloads/Abdul-Basit.mp3 > /dev/null 2>&1'

The code from prayTimes.org is really configurable, so you can change the prayer time calculation method and a whole load of other adjustments. 

5. Add a job in crontab to run this script on a daily basis to update the azaan times:

# m     h       dom     mon     dow     command
0 1 * * * python /home/pi/Documents/updateAzaanTimers.py > /dev/null 2>&1

6. You're done. For each prayer , the raspberry pi will play the azaan mp3 via the speaker.

For All code and audio files I've used/written are available on the link below:
https://www.dropbox.com/sh/r0e787digng1rgv/OmCXiu9Vx_/RPi%20Azaan%20Clock


#!/usr/bin/env python

import datetime
from praytimes import PrayTimes


#Get Prayer Times
#--------------------
lat = 51.5171
long = 0.1062

now = datetime.datetime.now()



PT = PrayTimes('ISNA') 
times = PT.getTimes((now.year,now.month,now.day), (lat, long), 0,1) 

print times['fajr']
print times['dhuhr']
print times['asr']
print times['maghrib']
print times['isha']


#Update Crontab with Prayer Times
#---------------------------------

from crontab import CronTab


#Function to add azaan time to cron
def addAzaanTime (strPrayerName, strPrayerTime, objCronTab, strCommand):

  job = objCronTab.new(command=strCommand,comment=strPrayerName)
  
  timeArr = strPrayerTime.split(':')

  hour = timeArr[0]
  min = timeArr[1]

  job.minute.on(int(min))
  job.hour.on(int(hour))

  print job

  return



system_cron = CronTab()

strPlayAzaanMP3Command = 'omxplayer -o local /home/pi/Downloads/Abdul-Basit.mp3 > /dev/null 2>&1'

jobs = system_cron.find_command(strPlayAzaanMP3Command)

print jobs

for j in jobs:
  system_cron.remove(j) 

addAzaanTime('fajr',times['fajr'],system_cron,strPlayAzaanMP3Command)
addAzaanTime('dhuhr',times['dhuhr'],system_cron,strPlayAzaanMP3Command)
addAzaanTime('asr',times['asr'],system_cron,strPlayAzaanMP3Command)
addAzaanTime('maghrib',times['maghrib'],system_cron,strPlayAzaanMP3Command)
addAzaanTime('isha',times['isha'],system_cron,strPlayAzaanMP3Command)


system_cron.write()

  4. Thanks so much! I will be integrating some of this code on my RPI and HomeAssistant to play Azan on my Google Home Mini and turn on SONOFF lights of certain portion of the house for several minutes

  5. Hi,
    I am working on a similar project but not getting the correct timings from prayertimes.py
    I tried to play with the parameters but could not tune it exactly. We follow these timings in our mosque:

  6. Hello, I have no experience with programming. I will not go beyond the fourth step. Could someone help me with this? Thanks in advance. Burak

  7. Check fiveprayers website for a free service to create prayer times display systems. All what you need is a TV screen (smart with browser) or with RP connected. No programming is needed at all. Again it is free (fiveprayers.org).

  10. As-salamu alaykum,
    You can turn your Raspberry Pi into an azan clock by simply running smartazanclock.com on it in kiosk mode. Full instructions are here:
    https://smartazanclock.com/diy-azan-clock-raspberry-pi-instructions It lets you manage the settings using your phone on the same network so it can run "headless" without a monitor attached to it.
