Description
Nixie Clock on IN-14 and Arduino v2
Boards:
- The dimensions of the board are less than 100x100mm.
- All components are output, soldered even by a beginner
- The number of components is minimized!
- The system consists of two boards: the bottom (all control electronics) and the top (lamps and backlight LEDs)
Hardware Chips:
- The heart of the board is the full-size Arduino NANO, which means easy assembly and firmware
- Power supply for the entire circuit - 5 Volts
- The high voltage generator is swinging the PWM channel of Arduino
- The voltage of the generator is adjusted by a resistor with a twist
- Time sets RTC DS3231
- 3 buttons for setting the time and alarm
- Alarm squeaker
- Illumination of indicator lamps
Software Chips:
- “Busting” the figures once every half an hour, preventing the indicators from oxidizing
- Smooth change of brightness of a point and illumination of lamps
- Setting the brightness of numbers, “dots” and backlight
- Two brightness modes depending on the time of day
- 4 indicator switching modes
- 3 lamp backlight modes
Button control:
Time setting:
- The left button is a choice, the rest are “more” and “less”
- Hold “selection” - time setting
- Click on “choice” - change the setting hours / minutes
- Click “more” and “less” - time change
- Hold “select” - return to watch mode
Setting effects. In watch mode:
The central button toggles the lamp backlight
- breath
- constant light
- off
The right button switches the modes of turning numbers
- No effect
- Smooth fading
- Number Rewind
- Cathode Rewind
- Train
- Rubber
Holding the center button enables / disables “glitches”
