  • How to use EV3/NTX color sensor ?

    Hi guys.
    We attached NXT color sensor to the Legacy Module.We also put the "EnableLED" block in, but the sensor didn't work and light were not on.We also tried the EV3 color sensor,but there was the same problem.
    We really need help.

    Thanks!

    The NXT and EV3 color sensors are not supported and cannot be used. There had been talk from Tom Eng about the NXT color sensor being added to the feature request list for a future software release, but nothing official has been heard on this topic for around a month now.

      If you mean the Hitechnic NXT color sensor v2, that one is supported and I've tested it. It actually performs better, in my opinion, than the Adafruit and MR color sensors. Just plug it into a legacy module and when you configure that port you'll see that one of the choices is "COLOR_SENSOR". If you look at the ColorSensorDriver.java example opmode, you'll see the support for all 3 color sensors (NXT, Adafruit, MR).

        This is correct. The NXT could use both the Lego color sensor and the HiTechnic color sensor. The Lego color sensor is not supported, but the HiTechnic one is. I wish that the choices in ColorSensorDriver had been (HiTechnic, Adafruit, MR) to be more clear about what is and what is not supported.

          Thank you! Maybe I can use adafruit color sensor(http://www.adafruit.com/products/1334)?

            Yes, you can get a lot of documentation from FIRST on the adafruit sensor here. The only real drawback is that you need to 3D print an enclosure for it and create your own cable that connects to the DIM.
