Does anyone remember HAD covering a project using light reflected onto LEDs at touchless buttons?
If I recall correctly, awhile ago Hack-A-Day covered a project using LEDs as buttons. From what I remember it was either a Cornell or MIT or other major university final project. Basically it used light refllecting from the LED back onto it as a form of light sensor.
Does anyone have the link?
