Here you will learn about the different components on the Arduino board and then you will install IDE software and learn the program structure.
First Step: get familiar with Arduino UNO Board. Have a look at this tutorial.
Second Step: set up and start experiencing IDE software. Visit arduino.cc website here.
Third Step: learn the Program Structure here.
Fourth Step: learn the data types that you will use during Arduino programming here. You will find the following pieces of information:
- Data Types
- Variables and Constants
- Control Statements
- String Object
- I/O Functions
- Advanced I/O Functions
- Character Functions
You can also use a very useful Language Reference on Arduino.cc website.
