OK, what PSU?  What 5V and Ground?  Is it some sort of Arduino?  If so, which one?

What LEDs are these?  What are the Web links that describe them?

What is it you are actually wanting to do?  :smiley-eek:

Hint.  Read the forum instructions about how to ask questions.

8 Digit 7 Segment Display Modules going to use 7 instead of buying a sepeerate 5v power supply ? As Ive herd the Arduino cannot power then thats why , asking if you can use the 5v from the PSU .

If you have 5 V regulated power, you connect it to the 5 V terminal (and the ground to ground) on the Arduino.
