user26311: Is there a way to route an analog signal from a simple temperature sensor through an ADC, MCP3008, into a digital pin. I have used all the analog pins on my Arduino  Mega 2560 and am trying to utilize all the digital I/Os. 
Any insights on the matter would be greatly appreciated.

user4143: The MCP3008 is an SPI device. You connect it to the SPI pins of your Arduino. Then you can read 8 analog channels through it.
It requires 4 pins: MISO, MOSI, SCK and a chip select pin.
