Introduction
Chances are, you might have seen one of those super cool and flashy Nanoleaf light panels in IKEA or on Amazon. They are a brilliant source of indoor lighting that adds character to a room, with aesthetics that you just can't achieve with a simple light bulb. They are even able to be voice-controlled via amazon Alexa or Google Assistant, etc.
In this Raspberry Pi guide, we'll show you how to build a mini replica of the Nanoleaf. To keep it all as compact as possible, we've chose to use the Raspberry Pi Zero W for this project. However, you can use other models of the Raspberry Pi with it by creating a larger enclosure. This is an intermediate project as you'll need basic soldering skills, as well as access to a 3D printer to create the enclosure for our replica. This guide continues on from our starter guide on TrinityPixel LED strips and Raspberry Pi.Â
