You can consider this the "official" answer based on the EV3 firmware source code. This file is used for scaling the values that you see in "Port View" on the EV3 brick itself. The NXT Light Sensor is defined in these two lines: 2 0 NXT-REFLECT 1 1 3 0 2 119 0x32 3372.0 445.0 0 100 0.0 100.0 20 0 pct 2 1 NXT-AMBIENT 1 1 3 0 2 119 0x30 3411.0 633.0 0 100 ...

Both the NXT and EV3 color sensors have the capability of reading the individual color components. The value read is not a voltage, but just a "percent" of reflected light of each color. For NXT-G, you can find a block here (the Color Range Block). ...

The only camera capable of connecting directly to the NXT is the Vision Subsystem for NXT or EV3: With modified firmware, it is possible to send images from the cam to the NXT to the computer. But trying to stream video via this technique is impractical since each frame takes about 30 seconds to send to the computer. If you had a connection over USB, it ...

The NXT works fine with EV3 motors, and will read them as NXT motors. EV3 sensors, on the other hand, do not natively work with the NXT, with the exception of the touch sensor. The reason for this is that, touch sensor notwithstanding, EV3 sensors use a hardware communication protocol called UART, which is not supported by the NXT. The NXT only supports ...
