Hello,

I am doing an electronic project about microcontroller-based prayer time clock system (Namaz). I want to design a Prayer Time Alert System.

I wish to doing this project with a PIC Microcontroller like PIC32, real time component (RTC DS1307) to calculate real time, ISD4003 or SD-card MP3 Player which can play Namaz audio file in 5 times, GPS module or Bluetooth Module which locate with precision the city of living and voltage regulator for power supply.

What kind of design did you advice for me to doing this project ? can you help me to choose components whom match with this project.

Kind regards

Why you specified the MCU to PIC32 family !?!
Actually, in my point of view you can use either 18F\16F family, it's will be more than enough for your project.
And regarding to the project parts you can find them all in the CYTRON website,
http://cytron.com.my/products
You can find the MCU's and each module of the project.
The MCU:

The RTC:

The MP3 player:

The GPS:

The Bluetooth:

And you can find more options if you have time to surf more on the website.

Hello,

Thank you for your replying and very useful information. I specify PIC32 microcontroller for his memory capacity and reliability.

I have another idea also, I ask in mind if it will better if I used NXP LPC4357 or LPC1857 microcontroller. This project is very complex

Kind regards

Hi mzimr,

You can try Arduino Mega 2560 as a main board. It has bigger flash memory and it is 5V logic. And I think it has enough peripheral to program RTC DS1307 (I2C), SD-card MP3 Player (SPI), GPS module (UART), Bluetooth module (UART).

Thanks.

Hello,

Thank for your reply Idris . I want to design my own board which includes MCU to control all parts of my project.

My question is about designing the electronic board of this project.

Which MCU is better for this application and how to calculate waqt time.

Kind regards

Which MCU is not very important, ex PIC16/PIC18 or Arduino Uno/Mega. You just use which you familiar.
The important is you start interface the module you want RTC, MP3 Player, GPS or Bluetooth.
Prayer time can do in database (insert in memory) or calculation by date and location.
Ex use database http://shahrulnizam.com/pic-project-jam-solat/

PIC32 is quite expensive, however if you are using PIC32 it has internal real time clock and calender, RTCC, You can probably play wave file directly using PIC32, its very powerful controller that run up to 80MHZ CPU clock for MX series.
most of the PIC can work with all the module. should be no problem, most of the time is hard time to code everything correctly.

PIC32 is running at 3.3V, do make sure that all the module is able to run 3.3V. if all the modules are running 5V then its better for you to use 5V controller.

to get start mayb you can try to do coding with Cheaper Arduino compatible board like CT-UNO from cytron to learn all the neccesary communication with all the modules that you will want to use, if the modules are running 5V

at lot cheaper controller has plenty memory not only PIC32.
