## Getting started
Since I have already sold a few exixe modules, here is a short introduction on how to get started with exixe modules:

### Wiring it up

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

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.
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.
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.
After making 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.
