Story

This was a fun and simple project targeted at starting your day the right way! The affirmation box uses an ultrasonic sensor to detect when a person is approaching and displays a random affirmation each morning. The most important part of your day is when you wake up and it's important to start it on a good note. To see more about how the affirmation box works, please check out the video below!
