Introduction
YaBilal.nl is my personal passion project that captures all the phases of cutting-edge product development: PCB design, low-level MCU coding, AWS Cloud orchestration, and IoT integration. Whether you live in Europe, the US, or anywhere in between, I’m confident YaBilal can bring the exact Azan times you need right into your home.
The Tech Stack Behind YaBilal
-
Custom PCB Layout
I designed and manufactured a compact PCB (approximately 7×5×4 cm) that integrates everything needed for audio playback and Wi-Fi connectivity. I made sure all major components—from power management to signal processing—flow together seamlessly. -
Low-Level MCU Firmware
The microcontroller at the heart of YaBilal manages communication with the speaker, interfaces with sensors and controls, and synchronizes with my cloud service. The firmware is fine-tuned to minimize latency and keep the overall system stable. -
AWS Cloud Backend
Behind the scenes, an AWS IoT backend continuously monitors all mosque prayer times, ensuring they’re accurate and updated hourly. Whenever there’s a schedule change—for example, during Ramadan or daylight savings—the cloud immediately pushes the updated information to every YaBilal appliance. -
IoT Integration
YaBilal uses a secure IoT protocol to exchange data with AWS. This means each device checks in regularly to retrieve the next Azan schedule, adjust for new mosques, or even update the local time offset. Whether you’re online or offline, YaBilal adapts to keep you in sync. -
3D Enclosure Design
To house all the electronics, I built a streamlined 3D enclosure that fits easily in your bedroom, kitchen, or living room. It’s small enough not to take up too much space, yet big enough to include intuitive volume controls and deliver a clear, pleasant Azan.
How YaBilal Works
- Select Your Mosque
Choose from a list of growing supported mosques. The cloud backend updates your device’s prayer schedule immediately. - Adjust Volume & Settings
A built-in speaker and simple buttons let you select the volume you want. - Enjoy Authentic Azan
YaBilal accurately plays the Azan on time, every time—no guesswork or generic approximations.
This close sync with AWS Cloud ensures errors or delays are practically eliminated. If your local mosque changes its schedule, the device is instantly updated.

Why I Built It
Living in Europe, I often felt disconnected from the Azan schedules in my hometown. I realized many other Muslims here (and in other parts of the world) face the same challenge. By merging the latest hardware, firmware, cloud computing, and IoT technologies, I brought YaBilal to life to ensure every user stays connected to their faith—no matter their location.
