• Linux
• Lua 5.3
• Tek-UI
• Arduino-compatible board
  • with DS3231 module connected
• StandardFirmata burned in board (delivered with Arduino IDE)

• Clone this repository.

• Delete cloned repository.

If you don't have Arduino or DS3231 and just wish to take a look at interface, checkout virtual_rtc branch.

1. Pre-flight checks.

   1. Connect board to USB port.
   2. Launch Arduino IDE and upload StandardFirmata snippet (it's under examples/Firmata/).
   3. Close Arduino IDE serial monitor window.
   4. Connect DS3231 module. Check wiring.

2. Run main file:

   $ lua run.lua

   It will try to open first existing /dev/ttyUSB port (n = 0, 7).

   If you have several Arduinos connected, add port name:

   $ lua run.lua /dev/ttyUSB2

If you use alarm and it have hour time, alarm will trigger iff hour is stored in same format as moment time: 12h AM/PM or 24h.
