Hallo guys.I bought one LCD with I2C modul and the only thing i know is that it can be used with only 2 pins. Please help me with telling me the wireing up and some example software so i can see how it works and start my projects.
It seems to me this pretty much explains it all;
No - on my screen i have "scl" and "sda" so this link doesent explay anything.Please help

I think you need to read the linked Adafruit instructions again. You missed this part which is on the page titled "Connect to I2C"
Connect:
DAT (SDA) to I2C Data (on the Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2)
CLK (SCL) to I2C Clock (on the Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3)
SDA will be pin A4
SCL will be pin A5
ok, but the software ?
