# No-Code Seedling Frost Alert Device with Adafruit IO and WipperSnapper ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/143/869/medium800/adafruit_products_IMG_1349.jpg?1776363054) Don't lose seedlings to an overnight frost, protect them by building a frost alert device! **In this project, you'll use a QT Py ESP32-S3 and Adafruit IO to build a project which ambiently glows blue when it is predicted to freeze overnight. When it glows blue, it's time to take the seedlings in overnight.** **This project is no-code and no-wiring**. The QT Py runs Adafruit's WipperSnapper firmware. You'll use the Adafruit IO website to configure the QT Py's onboard NeoPixel. Then, **you'll configure an Adafruit IO Action to fetch the weather** for your location at the top of the hour. If the overnight forecast is freezing, a command is sent to the QT Py to turn the NeoPixel a bright blue color. Additionally,  **it will also send out a text message to your phone - reminding you to take in your seedlings overnight**. Warning: This project utilizes the Adafruit IO Plus Weather Power-Up to fetch real-time weather data, so, an Adafruit IO Plus Subscription is required. This project WILL NOT WORK without an Adafruit IO Plus Subscription!

WipperSnapper connects to [Adafruit IO](https://io.adafruit.com/), a web platform designed ([by Adafruit!](https://www.adafruit.com/about)) to _display_, _respond_, and _interact_ with your project's data. Simply load the WipperSnapper firmware onto your board, add credentials, and plug it into power. Your board will automatically register itself with your Adafruit IO account. From there, you can add _components_ to your board such as buttons, switches, potentiometers, sensors, and more! Components are _dynamically _added to hardware, so you can immediately start interacting, logging, and streaming the data your projects produce without writing code. ![](https://cdn-learn.adafruit.com/assets/assets/000/143/870/medium640/adafruit_products_SCR-20260413-ofzl.png?1776364643) ## Parts ### Adafruit QT Py S3 with 2MB PSRAM WiFi Dev Board with STEMMA QT [Adafruit QT Py S3 with 2MB PSRAM WiFi Dev Board with STEMMA QT](https://www.adafruit.com/product/5700) The ESP32-S3 has arrived in QT Py format - and what a great way to get started with this powerful new chip from Espressif!

If you have  suggestions or general feedback about the installation process - visit [https://io.adafruit.com/support](https://io.adafruit.com/support), click _"Contact Adafruit IO Support"_ and select _"I have feedback or suggestions for the WipperSnapper Beta"._ ## Troubleshooting If you encountered an issue during installation, please try the steps below first. If you're still unable to resolve the issue, or if your issue is not listed below, get in touch with us directly at [https://io.adafruit.com/support](https://io.adafruit.com/support "https://io.adafruit.com/support"). Make sure to click  _"Contact Adafruit IO Support"_ and select "_There is an issue with WipperSnapper. Something is broken!"_ ### First, make sure that you selected the correct board on the board selector. Next, please make sure that you entered your WiFi credentials properly, there are no spaces/special characters in either your network name (SSID) or password, and that you are connected to a 2.4GHz wireless network. If you're still unable to connect your board to WiFi, please [make a new post on the WipperSnapper technical support forum with the error you're experiencing, the LED colors which are blinking, and the board you're using.](https://forums.adafruit.com/viewforum.php?f=66) ### Try hard-resetting your board by unplugging it from USB power and plugging it back in. If the error is still occurring, please [make a new post on the WipperSnapper technical support forum with information about what you're experiencing, the LED colors which are blinking (if applicable), and the board you're using.](https://forums.adafruit.com/viewforum.php?f=66) ## "Uninstalling" WipperSnapper  WipperSnapper firmware is an application that is loaded onto your board. There is nothing to "uninstall". However, you may want to "move" your board from running WipperSnapper to running Arduino or CircuitPython. You also may need to restore your board to the state it was shipped to you from the Adafruit factory.  ### Moving from WipperSnapper to CircuitPython Follow the steps on the [Installing CircuitPython page](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython) to install CircuitPython on your board running WipperSnapper. - If you are unable to double-tap the RST button to enter the UF2 bootloader, follow the _"Factory Resetting a WipperSnapper Board"_ instructions below. Uploading this sketch will overwrite WipperSnapper. If you want to re-install WipperSnapper, follow the instructions at the top of this page. ### Moving from WipperSnapper to Arduino If you want to use your board with Arduino, you will use the Arduino IDE to load _any_ sketch onto your board. First, follow the page below to set up your Arduino IDE environment for use with your board. [Setup Arduino IDE](https://learn.adafruit.com/adafruit-qt-py-esp32-s3/arduino-ide-setup-99bba7be-288a-490d-b27b-1e63d17882fc) Then, follow the page below to upload the "Arduino Blink" sketch to your board. [Upload Arduino Blink Sketch](https://learn.adafruit.com/adafruit-qt-py-esp32-s3/arduino-neopixel-blink) Uploading this sketch will overwrite WipperSnapper. If you want to re-install WipperSnapper, follow the instructions at the top of this page. ### Factory Resetting a WipperSnapper Board Sometimes, hardware gets into a state that requires it to be "restored" to the original state it shipped in. If you'd like to get your board back to its original factory state, follow the guide below.

To upgrade your account, visit [io.adafruit.com/plus](https://io.adafruit.com/plus). ## Configure the Weather Power-Up A perk of Adafruit IO Plus is the Weather Power-Up. With it, you can access hyper local, minute-by-minute weather forecasts (provided by Apple WeatherKit) and deliver it directly to your device. We're going to use the Adafruit IO Weather power up to look at upcoming forecasts to see if seedlings need to be brought in overnight to shelter them from the frost. First we need to set up your location in the Adafruit IO Weather Power-Up (if you haven't done this already). Visit the [Adafruit IO Power-Up page](https://io.adafruit.com/services) (or click "Power-Ups" on the header). Then, click on the Get Started button on the Weather Power-Up. ![](https://cdn-learn.adafruit.com/assets/assets/000/143/709/medium800/adafruit_products_SCR-20260413-okke.png?1776111691) Under "Current Locations", click "Add Location". ![](https://cdn-learn.adafruit.com/assets/assets/000/143/710/medium800/adafruit_products_SCR-20260413-olab.png?1776111807) Select a location from the map, or enter your own location in `latitude, longitude` format. ![](https://cdn-learn.adafruit.com/assets/assets/000/143/712/medium640/adafruit_products_SCR-20260413-oltc.png?1776111995) ![](https://cdn-learn.adafruit.com/assets/assets/000/143/713/medium640/adafruit_products_SCR-20260413-oltc.png?1776112013) While `40.6517,-84.00874` describes an exact location for a hyperlocal forecast - we'll need to refer to the location by name later in this guide.  Give the location a name and click Create. ![](https://cdn-learn.adafruit.com/assets/assets/000/143/714/medium640/adafruit_products_SCR-20260413-olwe.png?1776112055) The new location should appear below **Current Locations**. ![](https://cdn-learn.adafruit.com/assets/assets/000/143/715/medium800/adafruit_products_SCR-20260413-olzx.png?1776112287) # No-Code Seedling Frost Alert Device with Adafruit IO and WipperSnapper ## Configure an Adafruit IO Action Adafruit IO Actions lets you define the logic for this project without programming.
