![]() ![]() ![]() While compiling, several things happened: Well, you just successfully compiled C++ source code into a binary. Assuming there are no syntactic errors in the program, the console at the bottom should print out some information about the program size and memory. ![]() Let’s do a quick experiment first: start your Arduino IDE, open one of the example codes (e.g. Let’s take a look at how compilation works. Don’t worry, it sounds much more complicated than it actually is. To understand how exactly this happens, we first have to take a quick look at how C/C++ source code is compiled into a program. It is much easier to organize, debug and maintain multiple, split files, than a huge blob of code.Īrduino beginners should already be familiar with #include which “adds” the library to the main sketch. Dividing code into separate files is also a good programming practice. This is one of the reasons why Arduino programming is so easy for beginners – you don’t need to have a deep understanding of how a sensor works libraries will do most of the work for you. But, how exactly does that happen? And what is really going on behind the scenes when you #include a library and then press the “Upload” button? What do I need to get started?Īlmost everyone who has ever used Arduino has used a library. This means that when you use less sensors, the overall program size and memory usage will be smaller. One of the core features of this library is that the program size is noticeably minimized by only compiling the parts of the library that contain the code specific for the sensor you want to use. In Lightweight Arduino Library for ROHM Sensor Evaluation Kit, I introduced RohmMultiSensor – Arduino library that allows you to easily interface with multiple sensors in the ROHM Sensor Evaluation Kit.
