Learn Guide: IoT Battery Charger Monitor
Build an internet connected battery charger and monitor with Feather ESP32-S2 Reverse TFT, CircuitPython, and Adafruit IO. The on-board MAX17048 LiPoly battery monitor chip reads the batteries voltage and is displayed on the Feather ESP32’s built-in color TFT display. Use the on-board button to cycle between icons and text. The project uses Adafruit IO actions to receive an SMS text or email when the battery is fully charged.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Feather or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
