Raspberry Pi Adhan Clock

This projects uses a python script which automatically calculates adhan times every day and plays all five adhans at their scheduled time using cron.

Prerequisites

1. Raspberry Pi running Raspbian
2. I would stay away from Raspberry Pi zero esp if you're new to this stuff since it doesn't come with a built in audio out port.
3. Also, if you haven't worked with raspberry pi before, I would highly recommend using these instructions to get it up and running: https://www.raspberrypi.org/documentation/installation/noobs.md
4. Speakers
5. Auxiliary audio cable

Instructions

1. Install git: Go to raspberry pi terminal (command line interface) and install git

• $ sudo apt-get install git

2. Clone repo: Clone this repository on your raspberry pi in your home directory. (Tip: run $ cd ~ to go to your home directory)

• $ git clone git@github.com:achaudhry/adhan.git
• After doing that you should see an adhan direcotry in your home directory.

3. Go into adhan directory: $cd adhan
4. Open updateAzaanTimers.py in your favorite editor. For instance, nano is a simple one: $ nano updateAzaanTimers.py

Configuration

The original python script is super configurable. Please see the manual for advanced instructions. However, below are the three basic things you'll need to change to get it up and running.

• Set the latitude and longitude so it can calculate accurate prayer times for that location. Modify the following lines:

#Set latitude and longitude here
#--------------------
lat = 42.3601
long = -71.0589

• Set adhan time calculation method. Modify the following line:

PT.setMethod('ISNA')

Save your changes by pressing Control X and then Y.

Run it for the first time

Run this command $ python /home/pi/adhan/updateAzaanTimers.py. If everythig worked, your output will look something like this:

05:51
11:52
14:11
16:30
17:53

Script execution finished at: 2017-01-06 21:22:31.512667

If you look at the last few lines, you'll see that 5 adhan times have been scheduled. Then there is another line at the end which makes sure that at 1am every day the same script will run and calculate adhan times for that day. And lastly, there is a line to clear logs on a monthly basis so that your log file doesn't grow too big.

VOILA! You're done!! Plug in your speakers and enjoy!

Tips:

1. You can see your currently scheduled jobs by running crontab -l
2. The output of the job that runs at 1am every night is being captured in /home/pi/adhan/adhan.log. This way you can keep track of all successful runs and any potential issues. This file will be truncated at midnight on the forst day of each month. To view the output type $ cat /home/pi/adhan/adhan.log
