We'll do that by wiring up an MCP3008 chip to it. The MCP3008 acts like a 'bridge' between digital and analog. It has 8 analog inputs and the Pi can query it using 4 digital pins. That makes it a perfect addition to the Pi for integrating simple sensors like photocells, FSRs or potentiometers, thermistors, etc.! | We'll do that by wiring up an MCP3008 chip to it.
