Here is a short video of the updated version of Bright Words, which I’ve dubbed take.too. This version includes a three main updates.
First, the color controls have been changed from RGB to HSB (here is a post about the Arduino library that converts HSB values in to RGB). HSB is a much more intuitive and enjoyable way to control the colors. It easy to cycle through colors of the same brightness and saturation.
Second, the device is now wireless. I’ve added a bluetooth module that enables me to connect the bright words light box wirelessly to my laptop. I’ve written a simple processing sketch that enables me to control the color (using HSB), the strobe speed, and the scroll speed, direction and width. I’ve also included a feature that provides real time control of each individual led so that I can make the lights synch to music.
Third, and last, I have added scrolling functionality to the bright lights. It supports scrolling in either direction, as well as from the inside out and from the outside in. It also makes it possible to control the width of the scrolling lights. Check out the video to see the scrolling in action.
