I'm working on a Christmas light display that will feature addressable LED strips on my front lawn. My LED strips operate at 12V (using the UCS1903 chipsetUCS1903 chipset).
The issue is, I need to run a long cable from my Arduino Due and power supply to the strips in some places (approx. 10 metres at the worst case). At this distance, the strips light up but the lights don't change colour. I might be able to reduce the cable length by a couple of metres, but I see the same results at a length of 6m. I'm using this 3-core 1mm diameter electrical cable.
The 3.3v output from my Arduino is below what is recommended for the UCS1903, but I've also tried on a 5V Arduino without success.
My question is, what do I need to look at to achieve this distance? Is it a matter of upping the data voltage, or using a larger cable, or some other technique?
