Below is an example of how to create different constants and variables.įigure 6: Using the addOne() function Commonly Used Arduino Functions ![]() Variables usually contain sensor values and other values that need to have mathematical operations done on them. Variables contain data that WILL change while a program is running. Constants usually contain pin numbers or sensor threshold values. Constants hold data that will NOT change while a program is running. They need to be given a name so that they can be referred to later. Less than/greater than or equal to comparisonīoolean AND or Boolean OR Used to cascade multiple Boolean operationsĬonstants and variables hold data according to their datatype. The table below includes common operators. The results of these operations are usually stored in a variable. Operators perform operations on variables and constants. The table below includes the most basic and widely used datatypes.Įnglish boolean values such as TRUE or LOW must be in all capsĪ single character (‘c’, ‘A’, ‘5’, ‘?’, etc.)Ī sequence of characters (“Hello World!”, Comments are text that the program ignoresĭatatypes are the different kinds of data values that can be used, manipulated and stored using C++.Conditionals, loops, and functions are enclosed in curly braces. ![]() Every line must either end with a semicolon ‘ ’ unless it’s a conditional, loop, or function.The most intuitive way to think about programming is like building with LEGO blocks: certain rules must be followed and different building blocks can be used to build bigger parts. The Arduino programming language is based on C/C++, but it is designed to be simpler and easier to learn.
