Dekatron tubes controlled by Arduino

Tuesday, August 16th, 2016

Flathagen writes: Interfacing dekatron tubes with a microcontroller is fairly easy, once you understand how the tubes work. Threeneuron's Pile o'Poo of Obsolete Crap provides the necessary background information and schematics for making this work. I used two russian OG-4 tubes. I prefer the orange look of the neon tubes...
