Ghosting of upper right LEDs. #2

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
At all times two LEDs in the upper right corner are lit at all times. It
seems to go across all versions of Arduino that I've tried. It does not
happen if the refresh rate is slowed down to light only individual LEDs.
Only when it is refreshing at a decent rate.

At 01:13 into the demo video on this page:

You can see the two LED "half" on.  You can also see 3 other LEDs that are 
partly lit that shouldn't be. In other parts of the video you can see ghosting 
of other LEDs too.

Those are due to the LED connected to pin 13. If you cut the resistor out that 
goes to the LED connected to pin 13, then that gets rid of the constant path to 
ground. Afterward, you are just left with the two in the upper right corner.

I think this one is solved (besides the fact that you need to cut the on-board 
resistor). Please feel free to re-open if you are still having the issue.
