1. It is good to Update your operating system and restart the laptop before proceeding further.
2. Download and install Arduino IDE (162MB)
3. Install CH340 Driver
4. Physically connect Arduino Board to Laptop via USB cable
5. Open Windows Device Manger, note the COM port
6. Start the Arduino IDE app on your laptop
7. Select the Board: Click on Tools -> Boards -> Arduino AVR Boards -> Arduino UNO
8. Select the Port: Click on Tools -> Ports -> COM_n (n = The port number you noted from Device Manager)
9. Files -> Examples -> 01 Basics -> Blink
10. Make your own copy of the example, so that we may modify and save the changes
    (because the Examples are read-only files for reference purpose)
    Files -> Save As -> HelloWorld
    This will restart the Arduino IDE
    (You may close the previous Arduino IDE window) to save RAM
11. Click on Sketch Upload
12. Notice the LED on the Arduino Board, it Blinks !
    One second ON, one second off
13. Press Ctrl+J to hide the Output window on Arduino IDE
14. Modify line number 34. Replace 1000 with 200
15. Save, Compile and Upload the code to Arduino just by pressing the Arrow button on Top Left corner of the IDE
    
    Or press Ctrl+U to do the same
16. Notice the LED on the Arduino Board, it Blinks !
    One 100 milli second ON, one second (1000 milli second) OFF
17. Experiment with values on Line 34 and 36
18. Goto next exercise
