The I2C Bus (2)

The familiar two-wire bus is ideal for experiments and applications using a Raspberry Pi or on an Arduino.

The inter-IC bus, or I2C bus for short, is a two-wire bus designed for connecting simple peripherals that do not require rapid transfer of large amounts of data. In this three-part series we will look at the essential features of the bus and see how it can be used in practice with a Raspberry Pi, Arduino or other system.
