MCP23017 GPIO Extender,anion MCP23S17 is available for SPI bus.) The I2C bus allows the chip to be remote from the Raspberry Pi, requiring only a four-wire ribbon cable (power, ground, and a pair of I2C bus lines). This chapter explores the features and limits of this peripheral.

Real-Time Clock,mine the current date and time when it boots up. A 3 V battery attached to the DS1307 will keep its internal clock running for up to 10 years, even when the Pi is powered off. If you have a Model B, don’t feel left out. There is no reason that you can’t try this project too; a Model B not connected

Great Britain and the Unifying of ItalyThe VS1838B is a PIN photodiode high-gain amplifier IC in an epoxy package with an outer shield. It consists of three pins and is about the size of a signal transistor. This inexpensive part can be purchased for about $2 on eBay to give your Raspberry Pi the ability to read many IR remote-control signals.
