How to use Ardunio to listen on i2c bus mastered by 2nd Arduino?

allen13331 Level 3

I have just competed an i2c project running (8) DS18B20DS18B20 all over the house which displays the results on a 20x4 LCD. I would like to monitor the i2c results at additional locations. Is is possible to set the Ardunino to listen to the i2c line and report the results, without conflict? I am new to all this (not an EE or C programmer and 60 years old), and just starting this hobby as a newbie so it seems simple which means it is not. Can I use the i2c sketch that I use for the DS 18B20 and modify it to just listen? Any help would be appreciated.

 

Thanks.
