Doodle clock-robot using arduino
Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that’s been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it — a number beyond what he just erased.
