No-Code Seedling Frost Alert and New WipperSnapper Components. What’s new with Adafruit IO and the Adafruit Learning System.

Adafruit recently introduced a no-code Seedling Frost Alert device using the QT Py ESP32-S3 and Adafruit IO. This project helps protect seedlings from unexpected frost by glowing blue when freezing temperatures are predicted. It also sends a text message to remind you to bring your plants indoors, making it a handy tool for gardeners.
