Overview:

Two different programs were written for the microcontroller/display ESP32-2432S028R, commonly know as the Cheap Yellow Display (CYD).

One program provides inside & outside weather stats, and the other reports the top 10 headlines.

The PCB contains both a weather sensor and motion sensor and the CYD, of course.

Both sensors are used with Arduino code WM_32.ino for determining the inside and outside weather stats.

Only the motion sensor is used with Arduino code NT_50.ino for grabbing the latest news headlines every 20 minutes.

Weather stats  and news article titles are shown on the CYD's 2.8" TFT touchscreen display with an onboard ESP32-WROOM-32, and are stored on an onboard micro SD drive.
API calls for the current weather are made to Open-Meteo. Free service. No API key is required.

API calls for the latest news headlines are made to gNews. Free service but an API key is required.

Weather Measurements:

 - Date & time

 - Inside and outside: Temperature (C/F), humidity %, barometric pressure kPa

 - Current sky conditions, e.g., mist, cloudy, etc.

 - Wind, Wind chill / Humidex

 - Weather Forecasting includes daily and weekly  temp High and Low, PoP,  sunrise and sunset times

News Ticker Features:

 - Every 20 minutes the top 10 headlines are displayed on the CYD and saved to a daily .csv file on the SD. Duplicate headlines are removed from the SD

 - User can switch between News Online (default) and News Local (saved on SD) in the event the WiFi is not available

 - Tapping any article will force an email containing the news headline and URL to be sent to the user's phone, tablet, PC, etc.

Other Features:

WiFi SSID, IP address, channel, RSSI receive strength, transmit strength

Weather Monitor Arduino Code: WM_32x.zip. You will need to provide your WiFi's SSID and password.

News Ticker Arduino Code: NT_50.zip You will need to provide your WiFi's SSID, password as well as an API key.

NOTE: ChatGPT5 helped write the code. As such it is larger than the 1MB limit for the ESP32 so you'll need to change the CYD config.

            Partition Scheme: No OTA (2MB  APP / 2MB FATFS).
