What would be the most practical (and preferably cheapest) way to drive 3-4 nixie tubes from an Arduino Uno? I am looking for a setup that, once I make it, will make setting the nixie tube is as easy as a
Things to consider:
- Nixie tubes require high voltage to run
- Each tube would take a lot of pins if I had 1 pin per digit
- 3 tubes is an OK goal - that's a total of 30 different digits to turn on (more than an uno has!)
- Cost is a factor
If it is at all possible, it would also be useful being able to put all this into a library, so I could use it anytime with just
#include <nixie.h>, however this is not crucial.
EDIT: If you need specifics, I am looking to drive 3 Russian IN-1 tubes from an Arduino Uno R3, and I already have a selection of basic components (resistors etc) so you don't need to include them in the cost.
EDIT: OK, I have an idea. Can you literally just hook 4 Arduino I/O pins per tube up to a 74141, power the 74141 with 100-ish volts, and connect the outputs to the tube? Will this work? If not, why not?
Sorry if I'm missing the point of these IC's completely, but like I said I have been unable to find a tutorial or even an article that outlines how to use these.
