Chapter 10. A Practical Example
In this chapter, you will use what you've learned throughout the book to build a complete, practical application. We will cover the following topics:
- Building a simple weather station
- Getting the weather data online
- Implementing weather alerts
- Creating a web interface for configuring the alerts
