Hello dear readers,

I'm embarking on an exciting project: building a prayer clock to assist believers in keeping track of their prayer times. But I need your help! The programming aspect has proven to be quite challenging. The clock should calculate prayer times based on geographical coordinates and display notifications. If you have experience with microcontrollers and time calculations, I encourage you to reach out. Together, we can bring this project to life.

The goal is to have the clock display prayer times on its screen. The following code currently displays the time, but there's still much work to be done.

#include "RTClib.h"
#include "LiquidCrystal_I2C.h"

// Name des RTC-Moduls
RTC_DS3231 rtc;

// Name des LCD-Moduls
LiquidCrystal_I2C lcd(0x3f, 20, 2);

void setup() 
{
  // RTC-Modul starten
  rtc.begin();

  /*
    wenn Datum und Zeit nicht korrekt -> Datum/Zeit setzen
    Jahr, Monat, Tag, Stunde, Minute, Sekunde
    Beispiel:  2022 August 31. 10 Uhr 30 Minuten 30 Sekunden
    rtc.adjust(DateTime(2022, 8, 31, 10, 31, 30));
 */

  // LCD starten
  lcd.init();
  lcd.backlight();
}

void loop() 
{
  // aktuelle Zeit holen
  DateTime aktuell = rtc.now();

  // 1. Zeile
  lcd.setCursor(0, 0);
  char Datum[] = "DD.MM.YY";

  // Datum in String umwandeln und anzeigen
  //lcd.print(aktuell.toString(Datum));
  // Format der Uhrzeit festlegen
  char Zeit[] = "hh:mm:ss";

  // gemessene Temperatur in String umwandeln
  String Temperatur = String(rtc.getTemperature());

  // angelsächsische Schreibweise der Temperatur
  // . durch , ersetzen
  float temperatur = rtc.getTemperature();

  // Datum in String umwandeln und anzeigen
  lcd.print(aktuell.toString(Datum))+ lcd.print("    ") + lcd.print(String(int(temperatur)) + "\337C");


  // 2. Zeile
  lcd.setCursor(0, 1);

  // Sonderzeichen für ° = \337
  // Temperatur anzeigen
  lcd.print(aktuell.toString(Zeit));

  delay(1000);
}

Thank you for your support!

you'll probably find examples on line like Arduino clock with Islamic prayer times - Hackster.io

How much do you pay? USD please.

It sounds like a good idea for a phone app... That's assuming you want to make something small & portable.

I would indeed expect that there are several already.

Hi @mclovinnn0. This forum category is used for paid work. Please clarify whether you are making an offer to pay someone to assist you with this project.

If you are only interested in free assistance in doing the project yourself, we are happy to help you out, but I would move the topic to the appropriate forum category.

I have an old Siemens C55 that has one written in JavaME :slight_smile: )
