Meet HappyTapBot! 

This little guy is here for you when you are feeling stressed or sad! Whether you are grinding through an essay or cramming for a test, he is always ready to give you a high five for a boost of encouragement to get you through! I used an Ultra sonic sensor with a threshold of ten to communicate to the servo motor when something gets close enough. Once a person's hand is within range, the servo rotates -60 degrees to raise the arm for an enthusiastic high five to lift users spirits!
