- 2. Arduino is a prototype platform (open-source) based on an easy-to-use hardware and software. It consists of a circuit board, which can be programed (referred to as a microcontroller) and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to the physical board. The key features are − •Arduino boards are able to read analog or digital input signals from different sensors and turn it into an output such as activating a motor, turning LED on/off, connect to the cloud and many other actions. •control your board functions by sending a set of instructions to the microcontroller on the board via Arduino IDE (referred to as uploading software). •Unlike most previous programmable circuit boards, Arduino does not need an extra piece of hardware (called a programmer) in order to load a new code onto the board. You can simply use a USB cable. •The Arduino IDE uses a simplified version of C++, making it easier to learn to program. • Arduino provides a standard form factor that breaks the functions of the micro-controller into a more accessible package.
- 3. Arduino programs are written in the Arduino Integrated Development Environment (IDE). Arduino IDE is a special software running on your system that allows you to write sketches (synonym for program in Arduino language) for different Arduino boards. The Arduino programming language is based on a very simple hardware programming language called processing, which is similar to the C language. After the sketch is written in the Arduino IDE, it should be uploaded on the Arduino board for execution. Arduino programming Concepts Main parts • Structure •Values (variables and constants) •Functions.
- 4. structure consist of two main functions − Setup( ) function Loop( ) function Void setup ( ) { } PURPOSE − The setup() function is called when a sketch starts. Use it to initialize the variables, pin modes, start using libraries, etc. The setup function will only run once, after each power up or reset of the Arduino board. INPUT − - OUTPUT − - RETURN − - Void Loop ( ) { } PURPOSE − After creating a setup() function, which initializes and sets the initial values, the loop() function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board. INPUT − - OUTPUT − - Structure Void The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called.
- 5. Variables in C programming language, which Arduino uses, have a property called scope. A scope is a region of the program and there are three places where variables can be declared. They are − Inside a function or a block, which is called local variables. In the definition of function parameters, which is called formal parameters. Outside of all functions, which is called global variables. Variables
- 6. Functions allow structuring the programs in segments of code to perform individual tasks. The typical case for creating a function is when one needs to perform the same action multiple times in a program. Function There are two required functions in an Arduino sketch or a program i.e. setup () and loop(). Other functions must be created outside the brackets of these two functions. The most common syntax to define a function is −
- 7. Control Statements S.NO Control Statement & Description 1 If statement: It takes an expression in parenthesis and a statement or block of statements. If the expression is true then the statement or block of statements gets executed otherwise these statements are skipped. 2 If …else statement: An if statement can be followed by an optional else statement, which executes when the expression is false. 3 If…else if …else statement: The if statement can be followed by an optional else if...else statement, which is very useful to test various conditions using single if...else if statement. 4 switch case statement: Similar to the if statements, switch...case controls the flow of programs by allowing the programmers to specify different codes that should be executed in various conditions. 5 Conditional Operator ? :The conditional operator ? : is the only ternary operator in C.
