When you’re hearing about Nixie clock, what is you first reaction for it? Or, have you ever heard about it before?
For your information, a Nixie tube is an electronic device, which it’s mostly been used for displaying numerals or other information. The glass tube is usually contained a wire-mesh anode and multiple cathodes in the shape of Hindu-Arabic numerals. When you try to apply some power to one cathode, it will soon surround it with an orange glow discharge. The Nixie tube always filled with neon and a little bit of mercury or argon in Penning mixture at low pressure.
The main purpose of this project is to show you how to drive a nixie tube display with the help of a PIC16F84A simple microcontroller. This is a better version of Nixie clock, where there are 4 nixie tubes being applied in this project.
However, when you’re running the system, the numbers doesn’t seem to appear in the correct order, which the sequence was a little bit messed up as follows 0,1,2,3,7,5,8,4,9,6. Don’t worry, if you having this problem you can easily get the rid of it by recompile everything in ASM file again.
Furthermore, the multiplex lamp is made using the system for controlling a 74,141 applied PIC16F84A quartz resonator 3.2768 MHz.
