How to learn arduino easily.

Arduino is an opensource platform development board which can use for making  embedded system projects .We can make lot of  projects using the help of arduino board .Arduino board is mainly based on Atmel Microcontrollers .There is an IDE for doing programming to Arduino board .The programming is similar to C++  .The main site of arduino is given .http://www.arduino.cc/ .
                       The programming is very easy and we can study all the functionalities within 2 or 3 days.

For learning arduino programming there are some good youtube videos
Here are the links that i found for learning complete arduino programming
