Arduino code language tutorial10/2/2023 ![]() In the above example loop ( ) function is a part of execution block. The execution block hosts statements like reading inputs, triggering outputs, checking conditions etc. PinMode (pin-number, INPUT) // set the ‘pin-number’ as outputĪfter the setup ( ) function is executed, the execution block runs next. PinMode (pin-number, OUTPUT) // set the ‘pin-number’ as output This function has to be included even if there are no statements to execute. The setup function is used to initialize the pin modes and start serial communication. The setup function is the first to execute when the program is executed, and this function is called only once. Here, setup ( ) is the preparation block and loop ( ) is an execution block. Arduino programs have a minimum of 2 blocks,Įach block has a set of statements enclosed in curly braces: The structure of Arduino program is pretty simple. Now let’s discuss the basics of Arduino programming. Download the Arduino software (depending on your OS) from the official website and follow the instructions to install. The open source Arduino IDE runs on Windows, Mac OS X, and Linux. The first step in programming the Arduino board is downloading and installing the Arduino IDE. After the sketch is written in the Arduino IDE, it should be uploaded on the Arduino board for execution. ![]() The Arduino programming language is based on a very simple hardware programming language called processing, which is similar to the C language. Arduino IDE is a special software running on your system that allows you to write sketches (synonym for program in Arduino language) for different Arduino boards. After understanding the hardware of the Arduino UNO board in the previous article, let’s now get started with Arduino programming.Īrduino programs are written in the Arduino Integrated Development Environment (IDE).
