XXI Century Sundial by Alessandro

xxi-century-sundial-wall-clock-laser

The XXI Century Sundial is created by Alessandro using an Arduino microcontroller, a wall, and a laser. 

This is a simple project of a sundial wherein the pinion is replaced by a line LASER I took from a LASER level. The LASER is mounted on a RC servo which in turn is driven by a micro controller. The micro controller keeps the time and turns the RC servo accordingly. … Shorting pins 1-2 adds some life to the sundial and makes it count just the seconds. Hypnotic initially, then pointless.
