CHAPTER
FIVE
ADD LIBRARIES
5.1 What is Library?
A library, gathering some function definitions and header files, usually contains two files: .h (header file, including
function statement, Macro definition, constructor definition, etc.) and .cpp (execution file, with function implementa-
tion, variable definition, and so on). When you need to use a function in some library, you just need to add a header
file (e.g. #include <dht.h>), and then call that function. This can make your code more concise. If you don’t want
to use the library, you can also write that function definition directly. Though as a result, the code will be long and
inconvenient to read.
5.2 Add libraries
Some libraries are already built in the Arduino IDE, when some others may need to be added. So now let’s see how to
add one. There are 3 methods for that.
5.2.1 Method 1
Directly import the library in Arduino IDE (take Dht as an example below). The advantage of this method is easy to
understand and operate, but on the other hand, only one library can be imported at a time. So it is inconvenient when
you need to add quite a lot of libraries.
