This is an interesting little device for checking LEDs. It’s a great conversation piece and would make a nice addition to any workbench.

So [I’d] been wanting to build an LED tester for a while. It seems like every time I wanted to make a project involving LEDs, and when first powering up my circuit, of course the LEDs don’t light up. You know that it is probably in the wiring or programming, but you’re not quite sure if maybe the LED is bad. Now you won’t have to wonder anymore. And of course, I made it out of something fun…
