RGB LED 2x4m strips partially show wrong color or do not lig

Post by taxiplasm »

Hello everyone,

I have a problem with some LED strip's mounted on two identical art installation.
On each installation there is an external power supply and an Arduino Mega 2560, which is controlling 2 x 4m RGB Led 60 strips, for a total of 480 led per installation. Each installation has the same identical code and setup.

On the first installation:
- LEDs 398-to-480 show the wrong colors: they remain still on a rainbow-white, whereas all the others are working well and properly follow the code.

I run the stradtest on both installations and the problems are confirmed.
Any help would be really appreciated, since the opening is tonight...thanks!

Can you describe the power connection(s) to the strip?
