Now that you know how to create and use variables, how to wait, and how to turn on your buzzer, you have many options for improving this project. 

Maybe you can build an amplifier that makes your buzzer even louder. Can you compare the decibel levels for a plastic cup, a paper cup and a Styrofoam cup? Are there other materials to make the buzzer louder? 

Maybe you would like your program to do more when the timer signals. Try to make the buzzer get louder and louder the longer it is turned on, or customizing the tones it makes. Try turning on the blinkers or add some motor control to move the robot around. Your timer will be sure to get your attention right away!
