control a usb light

March 28, 2009 | 10:59 pm

I want to control a USB-led light (the ones that are used to illuminatre a keyboard like this one http://www.thisnext.com/item/D5A0CFC7/LapWorks-USB-Powered-Keyboard )
When a bang is received it should start to turn on and of for ten secnds and after that ten seconds stop flickering. What shoudl I do to achieve this?

Assuming you can simply send it 1 and 0, just create a combination of metro and counter to do this. Wondering how you talk to the light, through serial? Might take some fiddling to get it to communicate.

i’m investigating a similar issue.
the difference is that i want to control a LED board with about 16 LEDs on it. and be able to control each LED individually…

i’ll post if i find anything helpful.

Thinksamuel or anyone on this discussion figure this out? I’m looking into this as well.

Those little USB lights usually just tap power from the USB buss, and aren’t interfaced with USB in any way.
