Hello everyone,
I have UNO R3 and I am curious about can I use multiple sensor (for example one lcd display with i2c and one RTC module) at same SCL/SDA pin?
I just looked at circuito.io and it shows I can, but I want to be sure because I can't test myself yet.
Because it is designed to do just that. It is a bus where each device has its own unique address. You address the device you want to communicate with. This allows several devices on the same 2 wire bus. Just do not forget the pull up resistors. When you start testing do it with one device at a time and use the included examples until you get a few to work, that way you will be comfortable with the interface.
