In this project I will be showing you how to create a simple shock activated alarm bike lock. Like the name implies, it does create an alarm sound when your bike is being moved around with permission. Along the way we will learn a bit about piezoelectric discs, amplifiers and a simple logic circuit. Let's get started!
