Automated WiFi Enabled (IoT) Salaah/Namaz (Prayers) Timings Display – Your Feedback


Thank you for taking the time and effort to review this Project and provide your feedback and insights. You can skip the Background section below and jump to the main content titled Feedback. JazakaAllahu Khairan for your efforts.



It was sometime in 2012 when I saw this lovely Salah Indicator in Jame Masjid, Mallepally, Hyderabad, India:It was dammn beautiful & innovative around that time as otherwise, the only prayer clocks that we usually had were the ones that displayed the Azan times (shown below) and were predominantly used in Saudi Arabia etc where Jamath is based on the Azan times.

However, in the Indian subcontinent, most Jamath times are usually fixed (except for Maghreb) and the Salah Time Indicator by ( aimed to solve this very problem.

I was very much intrigued about this and me & Dad got talking and I eventually ended up asking the price of it. And the price he mentioned almost made me speechless for a while. It was ~ INR 48,000! I was like,😲!  Asked him if the Masjid folks themselves purchased it, and pat came the answer: “Nope, it was sponsored by a Company (RR Masala)”. Aah, there it is…

I wasn’t able to focus on work at Office the next day or so. This Clock’s picture would keep hitting my brain and I’d start thinking and pondering about it over and over. I had too much of these permutational & combinational thoughts and I decided I was going to make this myself, albeit at a much affordable price!

Game on!

Couple of months later (in 2013), this was my rude functional prototype:

The following framed clock will make the video above more understandable:

At around this time, I was contemplating Starting Upand lo and behold, I became an Entrepreneur & Founded PotentialLabs. Juggling between my day Job & Entrepreneurship made it very difficult for me to focus on bringing this Prayer Clock to market. Even though I quit my Job in Dec, 2014 to focus full time on my Company, I found it almost impossible to continue on this project, and before I realized, many years had passed and this clock started accumulating dust and dying away 😢.

However, I’d sometimes get guilty and emotional when I’d see one of the original Automatic Prayer Indicator Display in Masjids and lament at myself for not completing the Project & launch it in market. My  hands would always usually be full at my Startup and I couldn’t re-launch this project.

Fast >> 2018, my Startup was in auto-pilot mode for a while & I was working on some Wireless Full Color LED Scrolling Displays (buzzword: IoT Message Displays ;)). I was experimenting with different pixels, LEDs, Display units etc and I stumbled upon this P10 Red LED Display panel:

These are the ones usually used in those outdoor LED Signage/Scrolling boards you must have come across:

I initially discarded these as I was building full color WiFi Scrolling Displays.

Adding a (extra) Hardware Serial Port using I2C on Arduino or other MCU – SyedTips – 3

One cool thing/feature I learned from the Arduino Uno WiFi board was how to implement/add an extra hardware Serial Port to the existing MCU using a I2C to Serial Bridge.

The Atmega328P MCU on the Arduino Uno has only one Hardware Serial port. If we’re interfacing a Serial Device to this MCU and would also like to use Serial debugging, an option is to use SoftwareSerial (which comes with it’s own set of issues and limitations). A better option is to have an I2C – Serial Bridge that’d allow the host MCU to interface with another Serial Device.

The team did this splendidly and used this SC16IS750IBS to have the MCU talk with the on-board ESP8266 through this I2C to Serial Bridge.



You can read more about the implementation and details on the product page:


Part 0: Getting started with AWS IoT and Arduino (+ESP8266)

[7/June/2017]: I came across this post: I haven’t tried it yet. Pls let me know in the comments if this worked for you.

[31/July/2016]: I’m very Sorry. I couldn’t get the ESP8266 talk with the AWS IoT platform due to the ESP’s limited ability to support TLS 1.2 which is required by AWS IoT.

If you’re comfortable using the ESP SDK, something exciting just came up: –> an MQTT example with AWS IoT + ESP8266.

I’ll wait till someone builds a wrapper/library around it.

I’ve been thinking of using the Arduino MKR1000 instead with the AWS IoT. Let’s hope this get’s done quick 🙂

Pre.Scriptum: (Edit: 21, Dec, 2015)  Amazon released the AWS IoT suite of applications and services a while back and I now feel it’ll be more helpful if we base our tutorial on the AWS IoT platform. It’s a TODO for me and hopefully I’ll have something up and running.

I’ll be doing a series of posts on getting started with building IoT applications using an AWS EC2 Instance and an Arduino with ESP8266 WiFi Module. We’ll eventually delve into Raspberry Pi, MongoDB, Node.js, Dashboards etc as  the journey continues. Continue reading “Part 0: Getting started with AWS IoT and Arduino (+ESP8266)”

Sharing WiFi Internet connection with Raspberry Pi through LAN/Ethernet (Headless Mode)

Update 25th August, 2017: I haven’t tried this method yet on the recently released Raspbian Stretch version. However, one user has confirmed that the first method works on it. If it works for you, please let us know through the comments. Thanks.

Update 29th Dec, 2016: If you’re using the latest PIXEL Image, please make sure you enable the SSH Server by placing a a file named as ssh in the boot directory before trying any of the following methods. The SSH Server on boot has been disabled in the latest Raspbian image as a security measure. Read more about it here:

Update 9th July, 2016: I’m inspired by this method of SSHing into a Pi through the USB only and gonna tinker and see if we can get to also share Internet over to the Pi using only the USB. (No more messy LAN Cable 🙂 ). If you get it working, please share.

Update 10th July, 2016: I’m afraid, I won’t be able to get the above method running on a Pi 2/3 as it’s only supposed to work on a Pi Zero. If you have a Pi Zero and are interested in Sharing WiFi over USB, please check out

Updated 5th April, 2016 with Striner’s method

This post will allow you to share WiFi Internet connection of the PC/Laptop with the Raspberry Pi which are connected to each other through a simple LAN/Ethernet cable connection at each end.

What you want to do:

  1. Share PC/Laptop’s WiFi Internet connection with Raspberry Pi through LAN/Ethernet connected to Raspberry Pi

Making Android talk with Arduino through WiFi

After spending days and more than 11 hours straight today, we’ve finally got Android talking with Arduino via WiFi using the cute little RN XV WiFi module. What was considered to be a mountain turned out to be a molehill. The funny part is that this now looks more easier than the Bluetooth communication which I’m comfortable with. What we’re doing here is connecting the Arduino to an Android device which is configured as a HotSpot (a very cool Android feature from ver 2.2 onwards). Snapshot:

Android Arduino WiFi

I’ll be explaining in detail all steps, configurations and code in my next post since I’m very tired now having worked the entire day getting this working. It’s 2:30 A.M 🙂 Good Night
