Touch LEDs for Arduino

Most of the projects published in Elektor simply provide a solution to a problem or fulfil a need. Even though their designers have often tried to propose an elegant circuit or design an attractive PCB, the aesthetic effect of the project itself, if there is one, usually takes second place. One exception is the Monome open source project, a USB luminous matrix keyboard that was designed to be good-looking. Here, it’s the application that seems to have been relegated to second place.
