LEDs - Any good way to view and compare them without adding them to a switch?
« on: Mon, 03 July 2017, 16:49:13 »
Hey good people

I have a bunch of LEDs i bought random places for some upcoming builds, I am still a little new to DIY electronics
Just need a good advice how to "manage" your LEDs and view them turned ON, easy without putting them in a switch for testing colors and compare brightness etc.

Any good, lets say Usb tool out there?  :-*

just something that have resisters already and less time "source" consuming - pre built little usb power thingy :)

 

I need to get stuff sorted :p

FWIW I have a breadboard like you illustrated, but it has a power board plugged into one end.  I just use that with a resistor.  Simple and effective.

Cool!, i wanted todo that but it has been 15+ years since school i am just starting to get into diy hoppy electronics and learning again :) but since this is the way to go and more fun in what i ordered above :)

i would be able maybe to build one with something like THIS power supply module right? and just use the power from the usb? instead of 12v

Yep - pretty much exactly that one.

I do not have a suitable USB cable to power it, but I do have an old wall wart that happens to work well.

You can also change a couple of jumpers on it to switch from 3.3V to 5V.  I have mine on 5V.
