What is a Arduino ?
An Arduino is a single board micro-controller computer. That can be program by computer by the software called Arduino IDE.
The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the "Arduino language".
Its basically used for creating projects. By simply writing program and code in an Arduino IDE software after writing code we have to firstly connect Arduino to our computer and check the port and also check the proper board name in board manager section. And last verify the code then after upload the program. Then it will take few seconds to upload the program successfully. And then program will run in the board.
