Once you're happy with the LED, you can try hooking up a Nixie tube to the module. Always test your tubes first before soldering them to the module. You can do that by connecting the anode to +180V through a 68K resistor and touch each cathode with GND and see if the corresponding digit lights up.
### High voltage supply and tube testing
I suggest buying a premade miniature high voltage power supply to Nixie tubes like [this one](https://www.ebay.com/itm/DC-5V-12V-to-170V-DC-High-Voltage-NIXIE-Power-Supply-Module-PSU-NIXIE-TUBE-ERA-/322511957768?hash=item4b1735ef08:g:ftQAAOSwYTVZmjZb), they are not that expensive, pretty efficient, runs on 5V, and saves tons of trouble of designing one yourself. Just search "5V nixie power supply" on ebay.
Needless to say the high voltage needed to drive Nixie tubes is dangerous. Those high voltage modules above probably won't generate enough current to kill you, but you do feel a tingle if your finger is dry, and a rather nasty shock if it's damp, so do watch out where you put your fingers.
After you're sure the tube is good, you can solder it to the module. Look at the pinout in [technical_details.md](/technical_details.md), and double check the pins are in the right hole, the anode pin should be in the anode hole, and the rest of them lined up properly.
### Example Sketches
Once after that's done, connect the 180V output of the supply to the HV pin of exixe module, make sure your Arduino, high voltage supply, and exixe module all share the same GND, and try the [show_digit4](/arduino_examples/1_show_digit4) and [show_all_digits](/arduino_examples/2_show_all_digits) example next.

That's pretty much it! You can let your imagination run free now. You can probably adapt the functions in [show_all_digits](/arduino_examples/2_show_all_digits) for more complex display routines, or write some fancy crossfade transitions, whatever you want to.

And if you're not using Arduino, the code is simple enough to adept to other embedded systems, it's just plain C after all.
