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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
