Antoine - Software therapist<p>So I added a connector, plugged it to a controller and nothing happened.</p><p>I had a moment of doubt, maybe the whole thing was faulty.</p><p>Then I look closely at the first led of the chain, and one of the pin wasn't correctly soldered. </p><p>I fixed it, plugged it again, and boom ! \o/</p><p><a href="https://piaille.fr/tags/LedMatrix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LedMatrix</span></a> <a href="https://piaille.fr/tags/ws2812b" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ws2812b</span></a></p>

Antoine - Software therapist<p>I change the failing led, and some other but I still had some bad 'twinkling'.<br>I suspected (and hoped) the cause was bad leds as I had salvaged them from the previous prototype, they might have suffered.<br>So I solder another one with new leds, and no more twinkling. It works just fine!</p><p>(there is some brightness difference, but is because there is two kind of chips, the newer are brighter).</p><p>I'm really happy with this. I'm going to write some code to display stuff then It'll be time to think about the real version :)</p><p><a href="https://piaille.fr/tags/LedMatrix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LedMatrix</span></a> <a href="https://piaille.fr/tags/ws2182b" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ws2182b</span></a> <a href="https://piaille.fr/tags/esp8266" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>esp8266</span></a> <a href="https://piaille.fr/tags/pcb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pcb</span></a></p>
