A few weeks ago, I started dreaming up this wacky project. And now I have a fun flower-covered Spring Hoodie that lights up depending on the weather forecast. The components in the hoodie include an Adafruit Flora, a CC3000 WiFi module, and a lithium battery, all concealed inside an inner pocket. Eighteen NeoPixel LEDs are hidden inside of fake flowers covering the hood. I used two Old Navy hoodies, turning one inside out and putting it inside the other as a lining that protects and conceals all the wiring.
When I turn on the hoodie, the WiFi module tethers to my phone, and the Flora uses it to connect to a simple PHP web page pulling 3-hour forecast data for the predicted precipitation, temperature, and wind speed from the Open Weather Map API.
When the Flora is connecting over WiFi, the lapel flower glows green to show that it’s working. Once it connects to this web page and grabs the weather information, the Flora uses it to control the color, brightness, and rate of change of the LED flowers.
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
