Arduino Getting Started

Arduino is an electronic prototyping platform. It is an Open-source and users to create interactive electronic objects. Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. It supports various CPUs like Atmel AVR (8-bit), ARM Cortex-M0+ (32-bit), ARM Cortex-M3 (32-bit), and Intel Quark (x86) (32-bit).

Arduino IDE

You can download the software from official link Here

Installation

Click Arduino.exe file
Click I Agree
Select component to install
Click Close

Uninstall

Arduino files are found in 3 locations:

The installation folder
The sketchbook folder, and
The Arduino15 folder.

The installation folder should be removed when you uninstall but the other two folders remain so you will need to remove those also to get a completely clean install. The Arduino15 folder is located at:

Platform	Location (PATH)
On Mac OS X	X:/Users/(username)/Library/Arduino15
On Windows:	Arduino IDE 1.6.5r5 and previous :C:\Users\(username)\AppData\Roaming\Arduino15 Arduino IDE 1.6.6 and later: C:\Users\(username)\AppData\Local\Arduino15
On Linux	/home/(username)/.arduino15 (a.k.a. ~/.arduino15)

If you delete this folder then you will need to reinstall any Boards you have installed using Boards Manager after you reinstall the Arduino IDE.

The sketchbook folder location is set in File > Preferences if you have any sketches or libraries that you want to save in there then back them up before removing it.

Arduino language Structure

setup() – the setup() function is called when a sketch starts. (After each power up or reset). Use it to initialize variable, pin modes, start using libraries, etc.
loop() – its like a while loop

Minimum Code

//www.ArunEworld.com
void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Compiling

Connecting the Arduino Uno

Upload Code to Board

Binary File

Where the Binary file will be save in PC Its will by default in this location C:\WINDOWS\TEMP\Folder ("arduino_build_130419")

How do I remove a library from the arduino environment?

The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch. Import Library menu in the Arduino IDE. To remove a library, stop the Arduino IDE and remove the library directory from the aforementioned location
