faulty neopixel ring?

by mark_r_jarrod on Sun Aug 04, 2019 3:21 pm

i have purchased a neopixel 24 led ring and i find i can only get 1 led to work, using a 16 pixel ring with no changes to code works fine (obs 16 pixel as apposed to 24), i have soldered the connections to the 24 led ring and double checked for damage to circuit , poor joints etc but cannot find anything

would this indicate a faulty ring, or a mess up on my part code wise?

i borrowed the code superhero power plant code by tony sherwood for testing ,only changed the number of led's to 24 and pin assignment to 9

added pics so you see what i mean

As a test, try jumping the data output from the pixel that works to the data-in pin of the third pixel (jump over the first one that doesn’t work). That can give us more information about the nature of the problem.
