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)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
