I have removed some offensive or not useful comments. I would like to encourage everyone to abide by the following principle, adapted from the O'Reilly code of conduct: "[this forum] should be a safe and productive environment for everyone"

That's why it is a limited "limiting" resistor.

And yes, it turns orange just before the magic smoke comes out ;-)


Did you just burn a breadboard to prove a point about LED color?
I like the cut of your jib.
PS: Crocodile clips... :)


The breadboard is fine, there never was much current running flowing.

The LED and Resistor died though ;-)

The most interesting part was that both parts died, not just one or the other. We assume that 1 part fails, opening the circuit, and the other parts in the circuit are are spared, but clearly, in your demonstration both parts failed.

FWIW, I have LEDs running w/out resistors, and they have been running for months without failure. I had originally assumed that the LEDs or the arduino would fail, but not both. I keep waiting for the cube to die, but its been a few months now, and they just keep working. I wonder how long it will take to break 192 LED running 24/7 with one arduino and no resistors. What will break first the LEDs or the arduino? who knows maybe both!
