Some issues are extra enjoyable when there are extra of us concerned, and having fun with time within the pool is a type of actions. Figuring out this, [Bert Wagner] began pondering of the way to greatest coordinate pool actions together with his children and their neighborhood mates. Out of this got here the Splashflag, an IoT gadget constructed from the bottom up that gives enjoyable pool events and an excellent studying expertise alongside the way in which.
The USB-powered Splashflag is housed in a 3D-printed case, with a easy 2×16 LCD mounted on the entrance to show the notification. There’s additionally a small servo mounted to the rear that raises a 3D-printed flag when the notification is available in—drawing your consideration to it a bit extra than simply textual content alone would. Hidden on the again can also be a reset button: a protracted press factory-resets the gadget to hook up with a special Wi-Fi community, and a fast press clears the notification to return the gadget to its resting state.
Inside is an ESP32-S3 that drives the servo and show and connects to the Wi-Fi. The ESP32 is ready up with a captive portal, easing the gadget’s connection to a wi-fi community. The ESP32, as soon as related, joins an MQTT dealer hosted by [Bert Wagner], permitting straightforward sending of notifications by way of the online app he made to shortly and simply ship out invites.
Thanks, [Bert Wagner], for sharing the method of constructing this enjoyable, distinctive IoT gadget—you’ll want to learn all the main points on his web site or take a look at the code and design recordsdata obtainable over on his GitHub. Take a look at a few of our different IoT initiatives if this venture has you curious about making your personal.
