![]() ![]() It is only to help you understand the code. It is not exported to the processor, so it doesn’t take any memory space in the microcontroller’s memory. Comments are the lines that are used to notify the programmer of that particular code snippet. You can use it to write comments in the sketch. Without that library file, it would become incredibly difficult to implement GPS functionality. The serial connection to the GPS deviceĪll the commands like ss.read in the above sketch are courtesy of the library file we included in the beginning. This example includes the SoftwareSerial library so that its functions may be used to control a GPS. Here’s how you can include a library file in your Arduino IDE. Parameters: The library file is the additional header to be added. Each library gives you some additional access to the sensors and modules.Īkin to the #define command, there is no semicolon needed at the end of the #include statement. They are specially written for Arduino’s purpose. There are several libraries available online. It is one of the best features of the Arduino IDE. The question is, what? Well, you can use this command to include additional library files into your sketch for adding some additional functionalities. #includeĬlearly, this tells the program to include something. In this case, the compiler will replace the variable a by 3. Constant is the value that is used in the program. Parameters: variable is the name, that has to be assigned to the value. It has some special header files as zip files that are available online to provide specialised functions. The program is a set of instructions in embedded C. The Arduino program is usually written in the Arduino IDE.
