Do you ever make coffee or tea, and find yourself not being able to finish it all before it gets cold? Well here is your solution! The heat sensor in the tabletop works in conjunction with LED lights to visibly inform you when your drink is getting cold. Red lights indicate a hot drink, then as the drink begins the cool down the lights start to fade to purple then to blue. To complete this project we'll need heat sensors, as well as LED lights that change colors.
Optometrists recommend that you look away from your screen every twenty minutes, and exercise your eyes by focusing on something close and something far away to prevent eye strain and dry eye.

6. when both lights have been covered, the motor reverses
