Flip-flop óptico com sensor por led RGB, alimentação 2xNiMH

RGB led operates SR flip-flop by optical reflection. Due to the chip position of green and red(sensor) leds, finger approximation causes some reflection which triggers flip-flop transition. Despite blue led position, aligned with lens axis, it is kept turned on because it improves sensitivity. Triggering is almost independent of room light level.
