Arduino Made Easy(er) Lesson 04 - if for And while Statements

In Lesson 04 of Arduino Made Easy(er) we will use the if, for, and while statements in our sketch. The for and while statements allow us to step through a set of instructions for a given amount of times. This allows us to reduce the amount of lines of code required to perform certain tasks.

The if statement is used to test weather a condition is True or False. Whenever a condition is True, the code within the if statement is run before continuing to the next set of instructions. When the statement is False, the code within the statement is skipped and the following lines of code are run.

The same Fritzing diagram as in Lesson 03 is used in this lesson and some of the same code from the previous lesson is also retained for this demonstration.

An ambient light sensor will be used in the next lesson replacing the potentiometer. Check the Arduino page on our website for more information.
