Blink keyboard light - Disco light

As you know there is 3 LED in every keyboard.

1. NUM LOCK
2.CAPS LOCK
3.SCROLL LOCK

Now we are gonna make this light blink using WScript.

Note: before running this program you should know how to close the program.

To close the program open task manager(Ctrl+Alt+Del) and kill wscript.exe

1. Open notepad and write this code.

Set WEBCHILLER =wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
WEBCHILLER.sendkeys "{CAPSLOCK}"
WEBCHILLER.sendkeys "{NUMLOCK}"
WEBCHILLER.sendkeys "{SCROLLLOCK}"
loop


2. Save the file as “blink.vbs”

3. Open blink.vps file and see your keyboard LED light.
