Arduino as a development board .
I remember the day when I first time comes to know about the Arduino Uno board.
At that time I'm in 2nd year of my Btech course. Arduino is a development board which means it is ready to use . You just have to buy an Arduino board and read about its pin diagram.
Generally an Arduino board have an IC ATmega 328p, just download the datasheet of this IC and learn it . It contains 13 digital pin and few analog pins . It have Rx and TX pin acts as receiver and transistor.
It gives output as 3.3v and 5v. It is used for doing many projects based on embedded systems.
Arduino UNO is very cheap and easily available and very helpful for students to start learning projects making and it includes both the coding and hardware assembling so acts as a right tool to start your project making fun time.
