 Arduino Software (IDE)
Launch the Arduino IDE (1/3)
Name of Sketch
Verify: Compile Sketch
Upload: Upload the
program to the board
Code Area
Messages / Errors
New Open Save
Serial Monitor
A program written using Arduino
IDE software is called sketch.

9. 9
 Select your board
• Tool  Board: “Arduino/Genuino Uno”  Arduino/Genuino Uno
Launch the Arduino IDE (2/3)

10. 10
 Select your serial port
• Check the port in advance
− (Windows) Device manager
• Tool  Port
Launch the Arduino IDE (3/3)

11. 11
 Every sketch must have two basic functions
• setup( ) { }
− Called when a sketch starts
− Only run once
− Ready to work
• loop( ) { }
− Called after creating a setup() function
− Run repeatedly
− Actively control the board
Write codes (1/2)

12. 12
 Programming Language Reference
• Arduino Reference is installed locally
− Also available at http://Arduino.cc
• Help  Reference
Write codes (2/2)

13. 13
 Compile
• Compile the sketch after writing the code
• Checks your code for errors
Upload the program (1/3)
Click

14. 14
Upload the program (2/3)
 Upload
• Upload the program to the configured Arduino board
Click

15. 15
 Check & Feedback
• Check your board whether it works well or not
• If any problem, then revise the code or circuit you build
