help: LED dimming via light sensor
i have been unsuccessful in finding a way to duplicate a "screen" with LED lights. where LEDs act like pixels.. whether a 10x10 layout or much more. and each of those LEDs have variable values of brightness. so thats the output... the input would ideally be video but i think im getting ahead of myself, so what about variable light sensors..
so if each sensor was attached to an LED, and if the sensor saw saw 50% brightness the LED would put out 50% brightness, dark sensor equals dark LED and bright light on the sensor meant bright output from the LED and as much in between as possible.
any thoughts, opinions or suggestions? thanks, john.
