No. The light sensor can have the red LED either on or off - you can't set it to
"20%" or something like that, and there's no way to toggle the LED fast enough
to mimic or RCX-style IR message. But...
You could cetainly have a program constantly running on the RCX, looking for a
change in light level, and use that to sense when the NXT was turning its LED on
the light sensor on or off. With proper timing, the RCX could also turn the LED
on the old-style sensor on/off, (by switching between active and passive modes),
thereby signaling the NXT. People have used this before for RCX-to-RCX "secure"
communication, for instance.

Well, once you learn to use that you won't be limited to mechanisms like the
above... and you'll free up more sensor ports. Use it, if possible.

| Hello everyone: Is it possible for the NXT to send Run Program commands from the NXT to RCX via a light sensor? Here is an example: 1- The NXT Ultrasound sensor detects an object close by, triggers the NXT light sensor to light up at 20 percent (...) (18 years ago, 5-Oct-06, to lugnet.robotics.nxt)
