Arduino is an open-source electronics platform that can be used to read inputs like sensors or buttons and turn them into outputs like activating motors or publishing data online. It uses easy to use hardware and software that allows coding to be accessible and transferable using languages like C++. Common Arduino boards include the Arduino Mega, which has 54 digital input/output pins and uses an ATmega2560 microcontroller. To use an Arduino board, the Arduino IDE software must be installed to write and upload code to the board. Programming involves using data types, operators, control flow statements like if/else and loops, and defining a setup and loop structure.

5. Open Hardware
"Open hardware" or "open source
hardware," refers to the design
specifications of a physical object
which are licensed in such a way
that said object can be studied,
modified, created, and distributed by
anyone. "Open hardware" is a set of
design principles and legal practices,
not a specific type of object.

6. Open Software
Open-source software is computer
software that is released under a
license in which the copyright holder
grants users the rights to use, study,
change, and distribute the software
and its source code to anyone and for
any purpose. Open-source software
may be developed in a collaborative
public manner.

Processor
Coding is accessible & transferrable (C++, java)

9. Arduino boards are able to read inputs
- light on a sensor, a finger on a
button, or a Twitter message - and
turn it into an output - activating a
motor, turning on an LED, publishing
something online and much more ……..

13. Arduino Mega
The Arduino Mega 2560 is a microcontroller board based on the
ATmega2560. It has 54 digital input/output pins (of which 15 can
be used as PWM outputs).
FLASH MEMORY : 256 KB of which 8 KB used by bootloader
SRAM : 8 KB
CLOCK SPEED : 16 MHz

16. Installation
For giving instructions to our board we have to code for Arduino and
have to upload the code to our board . For writing and uploading the
code we have to download a software (Arduino IDE) and have to
install in our Desktop/Laptop . The software download link :
https://www.arduino.cc/en/software

18. Data Types
Integer : used with integer variables with value between 2147483647 and -
2147483647.
Ex: int x=1200;
Character: used with single character, represent value from - 127 to 128.
Ex: char c=‘r’;
Long: Long variables are extended size variables for number storage, and store 32
bits (4 bytes), from -2,147,483,648 to 2,147,483,647.
Ex. long u=199203;
Floating-point: Numbers can be as large as 3.4028235E+38 and as low as -
3.4028235E+38. They are stored as 32 bits (4 bytes) of information.
Ex. float num=1.291;

19. Statement and Operators
Statement represents a command, it ends with ;
Ex: int x;
x=13;
Operators are symbols that used to indicate a specific function:
- Math operators: [+,-,*,/,%,^]
- Logic operators: [==, !=, &&, ||]
- Comparison operators: [==, >, <, !=, <=, >=]
Syntax:
; Semicolon,
{} curly braces,
//single line comment,
/*Multi-line comments*/
19

20. Statement and Operators
Compound Operators:
++ (increment)
-- (decrement)
+= (compound addition)
-= (compound subtraction)
*= (compound multiplication)
/= (compound division)
20

21. Control statements
If Conditioning:
if(condition) {
Statements-1;
… Statement-N;
}
else if(condition2) {
Statements;
}
else{
Statements;
}
21

22. Control statements
Switch case:
switch (var) {
case 1: //do something when var equals 1
break;
case 2: //do something when var equals 2
break;
default: // if nothing else matches, do the default // default is optional
}
22

23. Loop statements
Do… while:
do {
Statements;
} while(condition); // the statements are run at least once.
While:
while(condition) {
Statements;
}
For:
for (int i=0; i <= val; i++){
statements;
}
23

24. Loop statements
Do… while:
do {
Statements;
} while(condition); // the statements are run at least once.
While:
while(condition) {
Statements;
}
For:
for (int i=0; i <= val; i++){
statements;
}
24

25. Code structure
Void setup(){}
//Used to indicate the initial values of system on starting.
Void loop(){}
//Contains the statements that will run whenever the system is
powered after setup.
