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)
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
