Making a weather monitoring system

In this section, we'll build a simple weather monitoring system. We'll use the skills that we've learned about, such as reading temperature and humidity from a DHT22 sensor device. Ultimately we'll be able to display the temperature and humidity on the LCD after reading from the sensor device.

Let's begin by creating a project.

Creating a project

To simplify our weather monitoring system project, we will copy the previous project named lcddemo and create a project called weather. Our main program is weather.c on the main folder. You can see a project structure shown in figure 2-16:

Now, let's move on to hardware...
