I am experimenting with getting two arduinos to talk to each other using the Wire.h library and I2C.
Has anyone created a tutorial yet that demonstrates code for a master and slave? From reading the forums it seems that some people have encountered problems using some of the functions if they did not insert adequate delays.
Will the library work only on analog pins? Can I change them from pins 4 and 5 to something else?
How come it does not use the internal pullups and I have to use external ones on the I2C bus lines?
