Kitty's Flowers is a pair of beautifully designed Bluetooth-wearable brooches, which can be programmed to interact with one another. The brooches are perfect for keeping loved ones by your side with Bluetooth connectivity. They are also a fun platform for kids to learn to program.

Jointly created by Art by Physicist (Dr. Kitty Yeung) and DFRobot, they contain an integrated power management system, RGB LED lights, an accelerometer, a touch sensor, and a vibrating motor. The brooches support Arduino and Scratch programming and can be used as the core intelligent control unit for wearable products, interactive art installations, and new accessories. The brooches come in matched pairs. Learn how to reprogram the boards on the Bluetooth Wearable Brooches product wiki.

In addition to being ideal for decoration and interaction, they are perfect for educational purposes for users who want to learn programming.
