Pater Practicus<p>Thanks to some really useful tip-offs, I've been reading up on <a href="https://mastodon.world/tags/Charlieplexing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Charlieplexing</span></a> (why is it even called that?), and I think it could be ideal for my model level-crossing lights. I've got three LEDs to control (amber and 2x flashing red) and it looks like I can control all three with just two GPIO pins on my Raspberry Pi Pico. Then, one of my 'wires' can be the hollow metal pole of the sign, with the other going up the middle - which would be perfect.</p>
