Artists have often found difficulties in drawing an arc or a circle with precision on sheets of different sizes. The smart compass is a simple mobile app based utility device that can draw arcs with different radii. The usage of servo motor in this project contributes to the accurate movement of the end effector (pen/pencil). The compass is designed to rotate to a certain degree specified by the user in the Mobile App via Bluetooth. Furthermore, a provision for drawing with three different radii is provided.
