The 18F452 and the 18F4520 have a built-in [[http://en.wikipedia.org/wiki/I2C|I2C]] (Inter-Integrated Circuit) bus.  I2C is a 2-wire synchronous serial bus.  Some devices, such as sensors, communicate with microcontrollers on this 2-wire serial bus.  Multiple devices, even different types of devices, can be attached to the same 2-wire I2C bus without causing collisions or errors.  Each device contains a unique address allowing multiple devices attached to the same I2C bus.  In our example, we will use a digital temperature sensor that communicates over I2C.
