Each file with Arduino code is called a sketch. The Arduino programming language is similar to the C++ language. In order for the Arduino IDE to compile the written code without errors, it is important to follow the pre-defined syntax. text/html 2020-07-20T09:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/programming_fundamentals_rtu/data_types_and_variable?rev=1595235600&do=diff Data types and variables Data types Each variable has its own data type that determines its place in the memory of the microcontroller and also the way how it can be used.

Digital signals can take two values - HIGH (1) or LOW (0). These types of inputs and outputs are useful in applications when the signal can have only two states. text/html 2020-07-20T09:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/programming_fundamentals_rtu/interrupts_and_sub-programs?rev=1595235600&do=diff Interrupts and sub-programs Functions Functions are the set of statements that are executed always when the function is called.

Although they might look similar, their functionality is different and should be used in different cases. delay() The delay() function pauses the execution of a program for a determined amount of time that is defined by milliseconds in the brackets. The down side of the delay() function is that none of the other program functions can execute while the time defined in the function is not passed.
