Hey, so I'm just playing around with a usb cable and an LED. I plugged in the usb to my computer and connected ground with the LED ground and the last usb pin (+) to the LED.
It stays lit bright. I moved the wire from the usb power pin to the D+ pin. Is it possible that I could send a bit stream through usb that would in turn light up this LED?
I'm not even a beginner with usb, drivers, etc. I just had the idea that hit me and wanted to see if it was possible as a sort of show off to friends.
