<!-- SC_OFF --><div class=“md”><p>Hi all, I've just got myself some ws2812b leds and learned about fastled. I'm using arduino UNO and I have been able to get some simple programs to work but I don't quite understand how I could dim and light up individual leds.</p> <p>I'm building lighting to my terrace and I'd like to use my laser cutter to make small lanterns out of plywood. Then I'd put couple of ws2812b leds in each of them and make them dim and light up slowly every once in a while. Doesn't have to be randomly.</p> <p>After getting that to work I'm planning to add IR sensor and when it detects movement all the lights will come on at max brightness.</p> <p>So there would be kind of a screen saver on when there's nobody around and leds would light up upon detecting movement.</p> <p>Could I get some help with dimming and lighting up individual leds? I have managed to play with "fadetoblackby" function but haven't figured out how to slow down dimming and how not to dim all the leds simultaneously…</p> </div><!-- SC_ON --> submitted by <a href=“https://old.reddit.com/user/nobiossi”> /u/nobiossi </a> <br/> <span><a href=“https://old.reddit.com/r/FastLED/comments/14ovi8h/blinking_stars/”>[link]</a></span> <span><a href=“https://old.reddit.com/r/FastLED/comments/14ovi8h/blinking_stars/”>[comments]</a></span>
