Azan Clock

This project is supposed to remind Muslims of their prayer times. Muslims are expected to pray five times a day. The "Azan" prayer call plays through the speaker when it is time to pray. The right prayer times are updated daily by using API calls. It can run on its own using a battery pack.

• Rasperry Pi Pico W
• Breadboard
• Speaker
• SD Card
• 1/8 Baltic Birch
• Battery pack (optional)

This project requires two API calls. One to get the current time and the second API to the get the prayer times. It is important to note that the community library for scheduling "circuitpython_schedule.mpy" needs to be imported. The two API Urls are the following:

• http://worldtimeapi.org/api/timezone/etc/gmt+4 (current time)
• http://api.aladhan.com/v1/timingsByCity?city=Boston&country=US&method=8 (prayer times)

The front has been designed by using Adobe Illustrator and represents a mosque. The design for the box behind was from boxes.py and uses a living hinge. Additionally, a hole for the speaker has been created. All the electronics are in the box. The different parts have been glued together.
