APA102 and fill_rainbow() #674
My first experience with electronic stuff and leds strip! (5m of 30leds/m => 150 leds) ( https://fr.aliexpress.com/item/1m-2m-4m-5m-5V-APA102-digital-smart-rgb-led-pixel-strip-light-30-32-60/32794298843.html?spm=a2g0s.90423220.127.116.11696c37u2EY2e https://fr.aliexpress.com/item/LAFVIN-De-Base-Starter-Kit-pour-Arduino-UNO-MEGA-2560-avec-Tutoriel/32869624633.html?spm=a2g0s.9042318.104.22.168696c37u2EY2e )
What I see: quickly a rainbow but the blue pixels become either red or green... so it is a mix between green and red.
What I did:
Since some colors changed into rainbow I tested different things, one of them is really strange for me:
and after some seconds some blue leds becames either red either green....
My questions are:
thank you for your help!!!!
What if you move the fill_rainbow and Fast.LED.show lines out of setup and into the main loop?
Also, how are you powering your pixels?
Probably not related, but did you run the FastLED RGBCalibrate example here:
