Hi, I have a very simple question.

Hi, I have a very simple question. I want to start a light display with one pixel switched on until a button press, like a standby light. How do I make just one led switch on?
I’m using ws2812 with arduino uno. Thanks

fill_solid( leds, NUM_LEDS, CRGB::Black);
leds[0] = CRGB::Purple;

Then wait for the button press etc. yes?

The key thing is to look at the numerous examples that come with the FastLED library, take them apart, learn how they work, and then re-write them to perform something different.

The examples a good starting points, as is the wiki https://github.com/FastLED/FastLED/wiki/Overview

Thanks guys, I worked something out from the blink example but I’ll try Mark’s example later too. Thank you :slight_smile:
