Introduction: Nixie Tube With Arduino

About: just share what i have to make life funny see my page

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

2. Nixie tube 6 pcs

3. Opto coupler chip TLP627

4. DC step-up module from 12VDC to 390VDC

5. Breadboard

Step 1: 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

Step 2: Arduino Code

This code will make counting for 2 nixie tube from 00 to 59 (like number of second and minutes).
