Nixie thermometer – let’s display the temperature

The design and development of this project is described in ten blog posts: for the chronological list follow this link

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):

nixie-28 nixie-29

nixie-30 nixie-31

The sketch is available on Github, here’s a video about how it works:
