It’s a pseudo-analogue connected device that gathers the current weather for any given location and shows you, in a very not-so-digital way, the results. No LEDs, no LCDs, just a simple, passive, wooden display.
The real point of this tutorial is to show you just how easy it is to connect a microcontroller to the internet and gather data. In this case, we’ll be looking at the OpenWeather API. They have a free tier, which is great, and the structure of their data is really easy to understand and implement. Think of this project as a starting point for connecting the virtual world with the physical. What you do next is up to you.
On the brains & connection to the Internet:
Building the circuit couldn’t be easier. We chose the Adafruit Feather HUZZAH because it has all the components we need to get connected to WiFi, and it can easily control a servo. Many other Arduino variants would work, as would many ESP8266 or ESP32 boards, but the Feather HUZZAH is our go-to board because it’s so simple, and it even has options for battery power, allowing for portability.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
