Hey everyone can you just give me brief idea how can i Design and implement a digital circuit which can display the KAMILAH with delay of 3 sec on seven segment displays. Implement the prototype first using Proteus and then translate it to the hardware.

You’ll struggle with the “M”

By lighting the segments make up the letters.

Your question is too general. What do you understand and what do you not understand.

I don't understand how to implement it on Proteus.Can you just explain me briefly.

The rules on Homework Help are different.
You have to show us your attempts at solving the problem and then we can guide you.

Hello,

Here is an "alphabet" for a 7 seg display:

Some letters will look weird as there can not be enough details on a 7 seg display.

Take any one case.
How would you display "P" on a 7-segment display?

Hi,I have tried to display numbers.Can you please guide me how to display letters.View attachment 313079
Did you succeed in displaying numbers? Do you think there is something different in displaying letters?

Numbers are displaying. Yes there is something different while displaying letters.

Obviously that isn't going to work. That decoder can only display numbers.

Have you designed synchronous counters and worked on designing decoders? Do truth table, kmap, or excitation table ring any bells?

SN7447 is a BCD to 7-segment display decoder-driver.
You need to abandon this part and create your own decoder. Do you know how to design a decoder from scratch?
Do you know how to draw a truth table?

It would be helpful if you posted the complete text for the problem.
