MCP3008, 8-Channel 10-Bit ADC With SPI Interface for Raspberry Pi

Description

Need to add analog inputs to your PI project, this chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. This a great accompaniment to the Raspberry Pi computer, because its fun to have analog inputs but the Pi does not have an ADC.
