Adafruit designed Raspberry Pi case, produced by others; Adafruit Raspberry Pi Cobbler or T-Cobbler; Adafruit Raspberry Pi Proto Plate; Arduino Nano; Dagu Sensor Pan and Tilt Kit; Integral 128gb usb memory stick; Interfacing push buttons on the Rapberry Pi using GPIO pins; MCP23017 16 Port Input / Output Expander I2C; MCP23017 IO Expander 16. The big difference with this line and previous examples is that the MCP23017 class. MCP23008 - i2c 8 input/output port expander. Using the adafruit library, you should be able to ignore the details of I2C communication, and just use the expander pins as if they were regular arduino pins.
