I have two of the led light belt kits and one five meter length of the same led strip.http://adafruit.com/products/332http://adafruit.com/products/306
I've taken the strip from the belt kit and wired it to an arduino uno, using:
int dataPin = 2;
int clockPin = 3;
const int numPixels = 32;
I have one of your 5 volt, 10a power supplies, which ought be enough to power a 5 meter led strip.
ground of strip to ground of arduino to ground of power supply
data pin 2 to strip, clock pin 3 to strip
power of power supply to +5 in on strip.
Works fine for the 1 meter, 32 led strip, but if I swap in the 5 meter strip I only see the first two led lights light up white. This is with updating the code to read:
const int numPixels = 160;
Is my five meter strip bad? I don't want to cut off the ends or anything, they are so nicely sealed and watertight.
The end I'm using is the end that was on the outside of the role, male pins, connects to the side of the leds where the connectors are labeled DI and CI.
Oh, the code I'm working with is the advanced led belt script.
