i installed what driver selection do I want to use for the 3535 size blinkytape leds?
doesnt work // FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
Which version of FastLED and Arduino are you using? The LEDs on that tape have SK6812 driver chips, which should work with the NEOPIXEL or WS2812 outputs on FastLED.
