Project 3: Motion

Tired of your cat walking all over the kitchen counter? How about the dog getting into the garbage? Need a way to stop your little brother from sneaking into your bedroom? Learn how to protect against all of these annoyances as you build a multipurpose alarm. The alarm detects distance and motion using an ultrasonic distance sensor, and creates motion using a servo motor.
