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 is compiled. The compiler does not know anything about the macros and never gets to...
Arduino Basics
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.
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.
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) { /* statement(s) will execute if the expression is true */ } else { /* statement(s)...
if, which is used in conjunction with a comparison operator, tests whether a certain condition has been reached, such as an input being above a certain number. If the expression.
The do loop works in the same manner as the while loop, with one difference in that the condition is tested at the end of the loop, so the do.
while loops will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something must change the tested variable, or the while loop will never exit. This could be in your code, such as an incremented variable, or an external condition, such...
Arduino for beginners : for loops The for statement is used to repeat a block of statements enclosed in curly braces. An increment counter is usually used to increment and.
In this example we use the RGB led again but are introducing a couple of new programming topis. We introduce the switch case structure and the random and randomSeed functions..
