Turn your door into an ‘alien portal’ using Arduino
Arduino Team — May 15th, 2017
As YouTuber Evan Kale puts it, his set is was kind of boring. He decided to spruce things up by turning his ordinary door into an “alien portal,” lining it with a strip of RGB LEDs. Though this may not be the first time you’ve seen this type of lighting in action, he directs our attention to a few interesting details about using them in typical Kale style.
One interesting note comes around the 4:50 mark, where he points out his portal is controlled using Hue Saturation Lightness (HSL) via a potentiometer instead of RGB. This keeps the glowing effect consistent, while allowing color adjustment.
For this project, he employed an Arduino Nano, which looks like a great choice since it needs a limited amount of I/O. Using this tiny board, the entire control package can fit into his small 3D-printed enclosure.
