This project creates a data visualization clock by using a Raspberry Pi and LEDs. When connected to the Internet, the Raspberry Pi can be programmed to capture real time or static data which can then be displayed on the clock face. The traditional clock face is represented with an RGB LED at each of the twelve numbers.

To provide the user with opportunity to learn manufacturing, electronics, programming, and research using big data.

• CAD program,
• Raspbian OS,
• Python

• Piece of wood (dimensions)
• 12 RGB LEDs
  • PTH Addressable https://www.sparkfun.com/products/12999
    • Raspberry Pi can not run these, so will need an Arduino interface or use different LEDs.
  • SMT RBG 5050 LED https://www.adafruit.com/product/619
    • These work with Raspberry Pi directly.
• Wires
• Raspberry Pi Zero W
  • microB to USB A adapter (https://www.adafruit.com/product/1099)
