The “Rythm Ring” is an interactive rhythm sequencer that is driven by a tangible interface, similar to the “BeatBearing” project that we covered here on Make back in January. This version is arranged in a circle with a central ring of LEDs that provide the user with live feedback for current “playhead” position with bright LEDs pulsing when a note is played due to a detected bearing. Check out all the details including code and circuit diagrams at the link below.
