LEGO robot with a split personality
Schizophrenic Arduino is a robot, that draws a line and erases it again. It is built from LEGO and controlled by an Arduino. When enough graphite of the pencil is on the paper, it closes an electric circuit, which causes the robot to stop drawing and to start erasing. Once the line is erased and the circuit is open again, the robot starts to draw again.
