Nixie Tube With Arduino
This project will show how to display NIXIE tube by Arduino and Optocoupler chip only. Nixie driver chip 74141 is difficult to purchase, so i decided to design a circuit with Optocoupler only. Fortunately, it works! After this experiment, i will try to make NIXIE CLOCK
Watch the video for full instruction
Part list to make the project:
1. Arduino UNO https://amzn.to/2P58O7s
2. Nixie tube 6 pcs https://amzn.to/3aHyJvX
3. Opto coupler chip TLP627
4. DC step-up module from 12VDC to 390VDC https://amzn.to/30kpdK9
5. Breadboard https://amzn.to/2uCrnsW
Circuit Design
As matrix design, we only need 12 output from Arduino to control 20 lights of 2 nixie tube.
By quick turn on and off 2 nixie tube, we will see two number as permanent view. The sequence turning on/off is by Arduino Code
Arduino Code
This code will make counting for 2 nixie tube from 00 to 59 (like number of second and minutes).
