Introduction
Have you ever wondered how automatic doors at grocery stores know when to open? There is a sensor over the door that works similarly to Go!Motion. Go!Motion sends out sound waves that reflect from objects, such as your body. Based on the amount of time it takes the wave to bounce back, Go!Motion is able to calculate the position of the object.
