Using Color Sensor from EV3 with Arduino

Other Hardware Sensors
1

Me and my bro are without a suitable color sensor to use for testing with the Arduino, so we decided to use a color sensor from the Lego EV3 kit, but we don't know how to make it communicate with the Arduino.
We searched the whole Internet and couldn't find how to do it...

  • We put together the 2 GND (red and black wire) and put them on GND.
  • The Power (green wire) we put in the 5v.
  • The Analog (white wire) we put in the A0.

We have 2 different sensors that we are trying to make work, the EV3 Color Sensor and the NXT Color Sensor.

ps: I did not know how it worked, but I knew a little about reflectance sensor, then I tried to use that I knew, but it did not work.

Below I have a picture of the color sensor and the connections we made:

We also saw this schematic about the cable that connects the Sensor to the EV3:

If someone knows how to do this communication, please help us :+1:
Thanks in advance.

I suspect you did not search the internet at all.

We have seen this project, but there are things in it that we don't have, like lego pieces, because we are avoiding using them, and want to use only the Arduino.

thanks for reply :+1:

The Lego world also use the word "Brick" for identification. Try looking for information on the IIC and Analog from the sensor. Try their FORUM or their SUPPORT

Did you see the user manual?
