Re: Help needed debugging interactive LED display

[glennkachmar]

OK, solved that one panel. Now I may debug the others a little.

Funny story: I wanted to check the LED collars as you suggested, but didn’t know what these are. So I googled “LED collars.” I don’t have a dog, but if I ever want to know what I need to walk one at night, I now have the answer. It brought me no closer to the solution though (but I figured it out).

The issue was some of the points where I soldered the leads – some were barely soldered in and one or two were black.

Thanks, by the way, for the help.
