Plumduino is a new mini RGB LED board which was inspired by the creator's kids who wanted to design their own nightlight. Plumduino has 8 RGB LEDs plus proximity sensors and a user-programmable button. It comes with pre-programmed lighting effects and can be programmed to create custom effects.
The device can be placed inside an object or project to create a custom light. And it's purple, we like that.
There's an optional expansion board too with more inputs and sensors.
