What is the difference between this and the light sensor demo?

the sensor that is being used can (and is )be used as a light sensor!

how is making the sounds with the flashlight

Hello Legoboy, Sorry I have not personally programmed a LEGO mindstorm but I can tell you a few things. Sensor: The design features a light sensor that has an output that varies with the intensity of the light. Computer: A computer has been programmed to read the sensor and respond by changing the frequency of a tone - this is likely a few lines of code. Speaker: The computer is connected to a speaker that produces the audible tones. Regards, APD

Is this a light sensor connected to a sound system?

The light sensor data wires were likely used to control the sound output, of a speaker. There is a video game, which uses this principle. I suspect that, in people, this "wire-cross" is the neurological condition synesthesia.

How does the sound react to the light?

The brighter the light the higher the pitch, the lower the light the lower the pitch.

What was the point of this video?

To show the capabilities of the light sensor.
