In the last video, we learned how to make multiple LED blinks. In this video, we will learn how to do programming in Arduino. How to take digital, analog, and serial inputs and where to store them? All questions will answer in this video.
Where can we write comments? We can write comments in starting, ending, or in between programming. Comments starts with // or /* and */. They do not affect code.
Operators : An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. Every operator is explained in a video.
Variables : A variable is a place to store a piece of data. It has a name, a value, and a type. There are three types of variables: Boolean, Integer, Character. How to define them? Watch the video to learn how to declare variables in Arduino.
After declaring, see how you can assign variables in Boolean, integer, and character variable. Where you are declaring variables is very important.
Now, what is Setup? The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup() function will only run once, after each power-up or reset of the Arduino board. See in the video how you can do every operation stated above, like how to pull up and pull down resistors, etc.
In programming, the ‘IFs statement’ is mostly used. We can use the Variation of ‘Ifs’ like conditional ifs, action ifs, and ‘else’. When you want repetition in a program, loops are used. A void loop is an example of loops where the bulk of your Arduino sketch is executed. The program starts directly after the opening curly bracket ( } ), runs until it sees the closing curly bracket ( } ), and jumps back up to the first line in loop(), and starts all over.
You can also use ‘for loop’ for repetition. It is often used in combination with arrays to operate on collections of data/pins.
After that, ‘while loop’ also performs a repetitive task in Arduino. A “While” Loop is used to repeat a specific block of code an unknown number of times until a condition is met.
So using all statements and loops, you can do programming in Arduino.
The most common uses of the Arduino are:
The Arduino comes with a number of different parts that are used in different ways. These parts include:
