Nixie Tube Driver Board for Arduino library (Omnixie_NTDB)

Released at https://github.com/omnixie-electronics/Nixie-Tube-Driver-Board-Arduino-Library short link: https://nixie.ai/ntdb4github

This Arduino library helps you make your own nixie tube clocks with ease. More tubes can be driven when multiple NTDB boards connected in series.

Two examples are provided:

1. A minimal 4-Nixie-tube display.
2. A complete clock using 4 nixie tubes, 3 tactile buttons and 2 colon bulbs.

In order to make a complete clock, you will need:

1. This KIT: https://nixie.ai/ntdb4
2. 4x nixie tubes
3. 1x NCH6300HV: https://nixie.ai/nch6300hv
4. 1x Arduino Uno board
5. 1x Real Time Clock module (DS1307, DS3231, etc)
6. Some jumper wires
