2. Digital Namaz Timing Clock
Project Scope:
We are creating Digital Namaz Timing Clock circuit in which it
shows following features it shows current time when namaz time
occur it create a beep for the users at Two minute which grape the
user attention about the namaz timing. This process repeats five
times a day.
Project Components:
 Bread Board
 555 NE
 4026 IC
 AND Gate (2input, 3input)
 Not Gate
 Resistor (50K, 1K, 330,)
 Capacitor (10uF, 1uF)
 Potentiometer (100K, 10K)
 Battery (9V)
 Regulator (7805 +5V)
 Simple Diode (1N40001)
 Seven Segment Display
 Push Buttons
 Wires

5. Digital Namaz Timing Clock Circuit:
 Timer Circuit
 7 Segment Display Circuit
 Alarm circuit
Timer Circuit:
 555 NE

6. 7 Segment Display Circuit:
 4026

9. Reset Seconds Logic:
We use B, E, E input to reset our seconds and add one minutes in our
minutes.
Reset Minutes Logic:
We use B, E, E input to reset our minutes and add one hours in our hours.
Reset Hours Logic:
We use C, E, F input to reset our Hrs.

10. Alarm circuit:
We use five alarms in our Digital namaz timing clock
 Fajar Alarm
6:00 AM
 Zuhr Alarm
01:30 PM
 Asar Alarm
04:00 PM
 Magrib Alarm
05:00 PM
 Isha Alarm
07:00 PM
Digital Clock Set or Reset:
We add two buttons in our circuit to set minutes and hours in our
clock. Hours button we use to set our digital clock hours and 2nd button is
use to set minutes in our digital clock and when we press our minute’s
button then our seconds 7 segment display automatically reset.
