I have an arduino uno and a 4x20 LCD with an I2C but I can't find any code for it. Anyone have any simple sample codes?
I tried that website and it wasn’t of much help. It is still not uploading

What is not uploading? Sounds to me like you have a compilation problem but you have provided no test code and no error messages.
Also, even if you had given code since you have shown no connection diagram and no reference to the device you are using (I know of 2 I2C LCD piggy back board types that have different internal pin assignments) so helping you find out what is wrong is next to impossible.
Did you download a new library or use the standard I2C library?
