This project is a data acquisition box using a Raspberry Pi and depending on the MCP3008 8-Channel 10-Bit ADC with SPI Interface (https://www.adafruit.com/product/856). It’s purpose is to help with data collection and plotting that data (using the free tool gnuplot), a series of buttons (for marking events such as start, stop, and important events), and a 16 Char x2 LCD display so that the Pi does not have to be hooked up to a monitor and keyboard to be used.

MCP3008 – 8-Channel 10-Bit ADC With SPI Interface: Need to add analog inputs? 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. We chose this chip as a great accompaniment to the Raspberry Pi computer, because its fun to have analog inputs but the Pi does not have an ADC. (read more)
