8.Arduino learning notebook--Digital dice experiment
Juvtmall ( a company supply PCB Prototyping, PCBA service and sell kinds of components, modules and so on)
Through the previous experiments of digital tube experiments and buttons that control leds, you should have learned the basic use of two devices. This time, use the nixie tube and button to make a simple digital dice.
The basic principle of the digital dice is that the nixie tube is quick to circulate between 1-8. When pressed, the nixie tube is fixed on the current number and don’t bounce.
Take a look at the wiring diagram:
