Alarm_Clock_Kettle

In this project, when an alarm clock is set, an audible alert sounds and a physical movement is triggered by a servo motor. Afterwards, the user can start a simple obstacle-avoidance game by pressing a button. It is both a fun and educational Arduino application. Further improvements will be made in the future.
