Today I wrote a sketch that merges the previous ones: reads the temperature from a thermistor (connected to PIN A0) and displays it driving two nixie tubes.
I also added a third nixie, to display symbol °C. This tube is not controlled by Arduino but it’s directly connected to the power supply (and therefore it’s always on):
The sketch is available on Github, here’s a video about how it works:
