I know how to use this chip with the Raspberry Pi thanks to Adafruit, but I am confused on how to add this to the Arduino (wiring and code) because of the pin layout in the datasheet. How do I add 8 analog pins to my Arduino Uno?
Thanks, any help is appreciated.

Re: Using MCP3008 with Arduino
The 3008 uses the SPI interface, so you'll want to use Arduino digital pins 10-13. Here are a couple of articles about using SPI with the Arduino:
This one talks about using the AVR's built-in SPI port: http://tronixstuff.BANNED.com/2011/0 ... e-spi-bus/
And here's one that shows examples of talking to various devices using SPI: http://tronixstuff.BANNED.com/2011/0 ... s-part-ii/
