This script allows you to control which capslock/numlock/scrolllock LED indicators are lit up, to produce effects such as flashing and cycling without altering the actual state of those keys (i.e. doesn't interfere with typing).

The script consists of 2 sections: 1) Some examples near the top. 2) The necessary functions.

The code originated here: Using Keyboard LEDs for spectrum.

Credit goes to Shimanov for the original code, Peter for syntax improvements and JGR for the code to get the handle of the keyboard device directly.

Here's a simple script I wrote to "disable" the NumLock LED on my laptop (it's quite distracting since I'm usually using an external keyboard and never change the status really). The script just checks the numlock state and if numlock is on it turns the LED off and vice versa (i.e. it becomes a Numlock-Off LED):

Wow this rocks, you're cool.
I don't have my other computer with the USB keyboard, so I'll have to try with it another time.
Thanks!

Aww it doesn't, but it works with your older version, must be some kind of detection. Like replacing the ACPI for HID :confused:

[evl]

Does it work on the USB keyboard if you change the 0 in "device =\Device\KeyBoardClass0" to 1 or 2?

I have a USB keyboard, but it doesn't have LEDs so I can't test.

[T-nm]

I'm pretty sure it can, but right now I can't. I'll tell you another time, maybe someone can try it out. My saitek gaming keyboard is usb only, can't use the adaptor.
There's also something funny when using the script, when the loop go too fast, like 100ms for each action it sometimes double a key when typing.

It uses the leds as spectrum, but only works with ps2 keyboards.

just tried it out... looks good! can be used for some mail notifications etc.

Any ideas of how to use it for mail notifications?

[evl]

There doesn't seem to be a particularly direct way with AHK (try searching the forums) so I guess the best way would be to retrieve info from a mail monitoring program with SetTimer (you could hide the window so it's not visible).

Omfg, i'm really mad, I dont know how to put this code into order so i can run it correctly... I WANT TO USE

Loop, 3 ; Knight Rider KITT cycling all LEDs

But how do i put it into the other code? can someone do this for me?¿?¿!!!

PLEASE.

You just need to put the following part where you want the changes to occur in your script:

cool.

way cool.

an interesting thing to do is to make a kind of "light tester"

with the following code the lights blink approximately at 60hz, thus if the keyboard is near a fast switching light like flourescent one or a strobe light, the light that is flashing out of sync is obvious.

{
method for additional security(?) :
ask user password- final digit is one two or three according to the "secret"
oddball LED (found by using a strobelight)?

of course this would be for simple security like for stopping kids from downloading games off of the internet (very very minimal security).

Sorry to dredge up this old thread, but I just got started with AutoHotkey and had the urge to make an LED show. I made it first without this script, and when I ported it, it became glitchy, especially with the NumLock. I will present both forms of the code and any help on the 2nd would be appreciated.

[engunneer]

Using the original script in the first post, it ran on my laptops's LEDs, and changing the device to Device 2, as evl said to do earlier, makes it work with my USB keyboard.

Oddly, one of the lights on my laptop didn't flash, since it doesn't appear to be one of the normal 3 lights. It's even hard to descibe what it does normally. I need to have numlock and this light on at the same time to even use the 'numpad' section of my laptop (normal keys in another use)

Thanks!

I don't suppose anyone has extended the code for the ThinkPad T60p with like 9 LED light across? I looked at the code and it's way over my head but just thought I'd ask.
