Jon<p>Rip puck of doom. This guy had a bunch of sensors inside and taught me how to use the Arduino cloud. I found that if I don't break things, even expensive things, I don't learn. I attempted to upgrade the puck with a GPS module, but it short-circuited the board with the 18650 battery, destroying both the microcontroller and half of the sensors on the shield. I was happy to avoid a battery meltdown! <a href="https://mastodon.social/tags/arduino" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>arduino</span></a></p>
