Top board not working


#1

Hi all,

I recently started working on the LED cube, but the top board is not working. I followed all troubleshooting steps, double checked all connections and solders, it all seems fine.

If I combine the LED blinking on the Arduino and the LED cube code together, the arduino light keeps flickering at regular intervals, so at least the code works. The LED board itself though doesn’t do anything…

I also tried changing the digital pin that the steers the LED cube, but that didnt help either.

Anything else I can try?

Thanks,
Philip

Philip can you take pictures of your cube?
Some of us had issues and it turned out to be our solder joints.

Hi Susan,

Thanks - attached some pictures. Do they look ok? I also checked with a multimeter and there’s no substantial resistance on any of the joints…
