Hey Everyone,
I made a neopixel powered desk lamp that is controlled by the Blynk app using a Photon. I wrote an app that turns the Neopixels on, but not all LEDs on all rows always turn on. It varies daily. I have checked the wiring and it’s solid.
Here are some pics:
I’m suspecting there is something wrong with how I send data to neopixels, any suggestions?
