Hi All
I purchased a range selection of these LEDs from Blip last week to test as potential 'runway' lights for the driveway at night.
I live in New Zealand (which is not part of Australia), and the goods arrived in only 3 days. Thanks Blip!
My first test was a string of 5 x 5V 8mm LEDs, these worked straight away using the example code provided by Ben. They are nice and bright too.
I then tried to test a string of 12V square lights. Powered them up with a 12VDC powerpack (and they all came on), but was unable to control them using the 5V digital outputs from my Arduino. The LEDs do not change at all. Was I wrong in hoping that the clock/data lines on the 12V LED devices could be controlled by the standard 5V Arduino output?
Another question - is it OK to increase the length of the cable run between each light, or is the circuit 'tuned' according to the cable length? (I'm assuming not, but am constantly proven that making ill-informed assumptions come back to bite!)
Thanks for your help. I'm a bit of noobie, so apologies for the rudimentary questions!
And great product by the way Blip. Cheers.
