If you’ve been waiting for a more detailed guide before you set off to work on your own Infinity Mirror, [Ben]‘s write-up is perhaps the most approachable one you will find. This build uses a set of four potentiometers to control an analog RGB LED strip (these lights are not individually addressable: but that makes coding simpler). [Ben] powers everything from a 12V 5A DC adapter, which is more than enough to run the 12V RGB strip along with the Arduino.
The mirror has two different ‘modes:’ individual channel color control and color-fade. In the first mode, three pots drive the RGB channels respectively. The color-fade mode has a mind of its own, sliding between all possible colors; you can spin the fourth potentiometer to control the speed of the transition.
The video below better illustrates the different modes. We definitely recommend [Ben's] excellent guide as an ideal first project for anyone who has yet to take the plunge beyond simple microcontroller exercises. Check out Freeside Atlanta’s Infinity Mirror prototype for more inspiration.
