Discussion Overview

The discussion revolves around the arrangement of LEDs on a breadboard to create a glowing display that spells out "SSUET." Participants are seeking guidance on circuit design and troubleshooting issues related to the simultaneous illumination of multiple LEDs.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses difficulty in understanding the accurate arrangements needed for the circuit to ensure all LEDs glow simultaneously.
  • Another participant requests a circuit diagram to better understand the current setup and suggests using simulation software like Multisim.
  • A participant clarifies that the goal is to spell out "SSUET" with LEDs and notes the substantial number of LEDs required for this project.
  • Information is shared about a website that helps calculate LED arrays based on voltage supply and LED specifications.
  • Participants discuss the university SSUET and its connection to the historical Aligarh Muslim University, providing context about its founders and significance.

Areas of Agreement / Disagreement

Participants generally agree on the need for a clear circuit design and the challenges involved in illuminating multiple LEDs. However, there is no consensus on the specific arrangements or solutions to the problem presented.

Contextual Notes

Participants have not provided specific assumptions about the power supply or LED specifications, and there are unresolved details regarding the circuit design and configuration.

I want to arrange LEDs on a breadboard want to glow SSUET entirely with LEDs.

The problem is that I am unable to understand the accurate arrangements to make the circuit. All of my LEDs are not glowing at the same time.

Can anyone please explain me the procedure of designing of the circuit.
I will be delighted for any help.

Post a circuit diagram so we can see what you already tried. You may also want to simulate your circuit using multisim or the like.
 
SSUET is a university in Karachi and you want to spell out SSUET with LEDs? Is that right?

This will take a lot of LEDs.

I found this site:

http://ledcalculator.net/

which seems to do a good job of working out these arrays. Click on the link to try it.

I started with a supply of 20 volts and a voltage per LED of 3.5 volts for white LEDs.

Thanks a lot, let me try out

You know this University ? !
:approve:
 
You know this University ? !

Sadly, no.
I found it on Google, but I now know more about it than I did before.

Unfortunately, we only ever see bad news stories from Pakistan, like earthquakes or train crashes, and all the good stuff stays inside your country. I would love to see Pakistan.

Who was Sir Syed, the SS in SSUET?
 
you might have heard about the Aligarh Muslim University in India, which was the first University in the sub-continent of its kind.

Sir Syed was the founder of that university is the 1890s and today, most of our experienced professors did their BS from there before going abroad for higher degree.

The SSUET, of which I am a part, has been established by a group of Old Aligarh Students who are also in the administration.


P.S:
Pakistan is a great country, its just the media which exaggerates everything up !
