Now you can go through the [provided Arduino examples](/arduino_examples). Try the [LED test](/arduino_examples/0_LED_test) first. Compile and upload the sketch, the LED on the exixe module should turn purple. You can play around with the RGB values in the sketch to change it to other colors.
If the board is not responding, take a look at the SPI commands in [technical_details.md](/technical_details.md) to make sure the SPI is configured properly. Use a logic analyzer to see what's going on if you have one, make sure the RST pin is HIGH, and CS pin is asserted properly.

### High voltage supply and tube testing
I suggest buying a premade miniature high voltage power supply for 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.
