It's time to get creative with LEDs thanks to the Brightdot Wearable Collection Brightdots are small and portable modules with one or more LEDs that need to be controlled by an Arduino-compatible development board. The entire collection includes a series of different modules with addressable Rgb LEDs that can be controlled individually. We've also developed a unique Arduino compatible that you can use to create something bright and portable that's also smart. This set includes 2 triple Brightdot strips and 2 five-fold Brightdot strips. Each PCB is super thin and includes gold-plated connectors with 6 1.22 mm (0.04 in) sewing holes. All models also have backup lines to ensure that one faulty LED doesn't affect the others. Each LED is controlled by 3 wires (power, ground, and data) and can be connected via these wires to the next LED, creating a large string of LEDs. You can solder these LEDs into electrical circuits, or sew them into clothes, on backpacks, on shoes, ...
