Arduino for beginners : Define

WARNING: Preprocessor macros, although tempting, can produce quite unexpected results if not done right. Always keep in mind that macros are textual substitutions done to your source code before anything.

Arduino for beginners – functions

When we create a function, it must be given a name. The naming convention for functions is the same as for variables: •The function name can be made up of alphanumeric characters (A to Z; a to z; 0 to 9) and the underscore (_)....

Arduino for beginners – setup and loop

The most basic Arduino sketch consists of two functions called setup() and loop(). The Arduino IDE once installed has a basic example that shows this. Open the Arduino IDE and select.

Arduino for beginners – if / else statement

An if statement can be followed by an optional else statement, which executes when the expression is false. Syntax The syntax of an if...else statement is [codesyntax lang="cpp"] if(expression) {.
