An UNO Mini Restricted Version necklace is a must have accent for Arduino lovers!

When Katie Dumont of element14 Presents obtained her Arduino UNO Mini Restricted Version, she was involved that it might find yourself like most of her different items of {hardware} — both saved someplace safely in its field or on a shelf for show. However as a result of she needed it to keep away from this destiny, her different thought was to function it prominently inside an amusing wearable.

For her undertaking, a collection of LEDs could be the principle output as their coloration and animation could be modified dynamically. Along with the lights, the necklace was deliberate to incorporate its personal LiPo battery pack for max mobility, though it might not function any consumer inputs in order that house may very well be saved. Every of those parts had been rigorously specified by FreeCAD and had a case constructed round them, which exposes the aspect of the pendant in order that the LEDs can emit a faint glow onto the shirt materials beneath, whereas the UNO Mini is entrance and heart.

The machine’s code is predicated on the preexisting Adafruit NeoPixel instance, because it accommodates the standard rainbow and stable coloration modes. As a result of the highest pins of the Uno Mini are uncovered, connecting one in every of three digital inputs pins to floor will make the board enter a selected coloration sample, in any other case it reveals a default rainbow one.
