Today I completed the prototype of my Nixie thermometer.
First, I put some heat-shrink tubing around each RGB led, to be sure that the light is emitted only upward and that the tubes are illuminated through the holes in the PCBs:
Then I wrote a sketch that includes all the previous examples, including the cycling (everytime you press the button) of the leds’ colors. You can download the final sketch from my Github’s repository.
Here are some shots and a video about how it works…
