Online Weather Display Using OpenWeatherMap

As a follow up to the first DIY project (Room Thermometer), we write a sketch that communicates with an online weather service (OpenWeatherMap) which provides the weather data for just about any city. We use this information to display the temperature, humidity and weather conditions to an OLED module.
BONUS: We also talk to the TeamTrees website and obtain the live tree count as an example to talk to webservers that do not provide a JSON response.

Step 1: Watch the Video

Since this project requires you to set up and obtain an API key along with other tasks, I would recommend you watch the video to get an understanding of how it all flows together. The video also breaks down the sketch to make it easier to understand.

Step 2: Download & Update the Sketch

The video covers this topic step-by-step but you need to obtain the API key from the OpenWeatherMap website in order to access the weather information. Once that is done, download the sketch and update it and don't forget to update your city details.

Step 3: Wire Up the OLED Module & Upload

Simply wire up the OLED module to the Nano 33 IoT board and upload the sketch.

Step 4: Bonus: Obtaining the Live Tree Count

The video covers the logic behind this, but you simply need to download the sketch, add your WiFi network credentials and upload it to your board. There is no need to obtain an API key for this sketch.
