EV3 IR, ultrasonic senosor documentation

Hi guys,

I want to connect EV3 IR and ultrasonic sensors to my Arduino. Unfortunately I could not find any good documents describing how to use/control these sensors.

For example after connecting EV3 IR sensor to my Arduino what will I see in the serial terminal.
How can I check that UART communication with the sensor is working.

Could you please help?

Thank you very much.

You better ask such questions in a Lego forum, perhaps people there have more information about the processor-sensor communication.
