HI there,
I'ḿ using a apa102 ledstrip with 476 leds.
I soldered the corners and powered my leds with a 5v 20a powersupply and control them with a arduino uno.
Unfutunately the leds aren't blinking as it should be.
For the first time all the leds where blinking but after that not al the leds are blinking anymore sometimes only the strip on the top and right sometimes only the bottom strip.
I tried some examples within the arduino IDE with APA102 library but still not al leds are blinking.
i was thinking if that the leds are underpowered or maybe the arduino can handle that many leds....
Is it better to use a powersupply 5v 30a and a arduino mega 2560?
Thanks!
