  1. Hi!

    I'm trying to setup the Line Sensor Array for my ev3 project but when i'm callibrating it, someting is wrong. 

    I've tried to read the sensors values (after running the calibration program) but i've got always ZERO values for the sensors readings. 

    I already checked the connections, the i2c port (default 20)... 

    Plz, help me with any idea!

    Thanks a lot!! :)

    Be sure to follow the instructions very carefully, and make sure when you calibrate the sensor you are using the same lighting conditions and space from your target as when you test. It is also a good idea to use a more matte finish. This reduce glare on the sensors.

    Also, check the firmware version of the device. If it was purchased a while back or from one of our vendors, it may have an older firmware that is not compatible with the EV3. Check the firmware using these instructions.
