Beat Buddy is a fun, assistive device designed and constructed for the Victoria University of Wellington Physical Computing course (MDDN251). Beat Buddy can be placed on any firm surface to detect when the user taps on the desk. These taps and knocks are then fed into a companion program where they are recorded as beats and looped. The companion program also displays the loop in such a way that the user's beats become a generative art piece. Beat Buddy is powered by an Arduino Pro Mini and the companion program was written with Processing.
