Chapter 1. A Simple Alarm System with Arduino
I want to start this book with a simple project that any secret agent will want to have, a simple alarm system that will be activated whenever motion is detected by a sensor. This simple system is not only fun to make but will also help us to go over the basics of Arduino programming and electronics, which are the skills that we will use in this whole book.
It will basically be a simple alarm (a buzzer that makes sound, plus a red LED) combined with a motion detector. The user will also be able to stop the alarm by pressing a button.
We are going to do the following in this chapter:
- First, we are going to see what the requirements for this project are, in terms of hardware and software
- Then, we will see ...
