Driving VFD tubes with an Arduino Nano

A simple method for incorporating vacuum fluorescent display tubes into your projects!

I’ve had a handful of Soviet-made IV-6 (ИВ-6) tubes sitting around my workshop for years, but I never really tried to get them working for any of my projects. But when I recently started restoring a Soviet-made variable transformer, I realized they would would make a good solution for displaying the voltage output level. So I built this driver circuit to get them going, with the idea that it could be applied to a wide range of future projects. I happen to live Tbilisi, Georgia (formerly a part of the USSR), so these tubes are relatively easy to come by, but they are also sold widely on eBay.”
