Digital Vibration Sensor Using LM358

Working with sensors makes electronics better and easy to work with, there are thousands of sensors to choose from and designing sensors would make for cool DIY projects.This instructable will be a part of a series of instructables in which I show you how to build sensors compatible with most microcontroller you can find. In the last two instructables I showed you how to how to make a tilt sensor and how to make a Touch sensor. In this instructable I will show you how to build a vibration sensor, which could be used as a part of a security system.”
