A prototype demonstrates how programmable objects can provide soft visual cues to help new learners.

An electrical engineering student at the University of Illinois at Chicago has built a guitar with LED lights embedded into the fretboard, which communicate with a programmable Arduino microcontroller built into the guitar's body. The guitar can be programmed to light up the fingerings of chords and arrangements, giving new guitarists simple visual scaffolding for developing their skills.
