Arduino uses a simplified version of the C/C++ programming language. It has an easy-to-use programming environment with pre-defined functions and libraries. 

Arduino programming language can be divided in three main parts: functions, values (variables and constants), and structure.

Here are some basics of Arduino programming:
Define your program
Declare inputs and outputs (I/O)
Create methods
Call methods in loop()
Upload the program to your board
Select the serial port
Debug code
