Spartronics countdown clock

Counts down the time until events such as kickoff, first competition, etc. Scrolling message is supported which is set via the mode button

Parts

  • Teensy LC
  • Adafruit NeoMatrix
  • DS3231 RTC
  • AT24C32 for storage -- currently not used

Libraries

Usage

  • 3 buttons control the behavior of the display

    • Mode - Change between countdown and messages
    • Inc - Change between countdown and date/time
    • Dec - Display the name of the next event

  • To set the clock (ie, adjusting for daylight savings)

    • Connect a computer to the USB port of the clock module
    • Load the Arduino IDE, and select the port where the Teensy is connected (Tools -> Port)
    • Start the Arduino serial monitor (Tools -> Serial Monitor), and set data rate to 115200bps
    • On clock module, change mode to time display by pressing Inc twice
    • While the time is displayed, click Mode twice (quickly)
    • The words SET TIME should be displayed in red on the clock, and a prompt message should be displayed o the serial terminal
    • Using the serial terminal, follow the prompts and enter the time in the format YYYY:MM:DD:hh:mm:ss
      • The date can be copied to clipboard on Mac with the command: date +%Y:%m:%d:%H:%M:%S | pbcopy
    • If successful, the new time should be displayed. Otherwise, you must re-enter time setting mode and try again

Building and Loading Code

TBD

Future Enhancements?

  • Use the EEPROM on the RTC board to store message strings that can be updated via the serial terminal
  • Use the EEPROM on the RTC board to store upcoming countdown dates that can be updated via the serial termanal
