= Nixie Library for Arduino =

With this library you can easy develop software for Nixie Clock and create
interesting sound and visual effects. The library contains all required
modules to communicate with different peripherals hardware (RTC, sensors,
tube drivers). The library was tested on Attiny85, Attiny45, Atmega168
and Atmega328p controllers. Nixie Library includes faster digitalWrite,
analogRead functions implementations (nixiePinLow, nixiePinHigh,
nixieAnalogRead) for Atmega328p controllers. The library uses millis() and micros()
functions. So, if you change TIMER0 settings, this will affect NixieLib behavior.
If you have questions, please contact via email.

Now the library contains full-cycle example of Nixie clock with schematics, layout, full source code.
Refer to https://github.com/lexus2k/NixieLib/tree/master/examples/nixie_clock_in14_v1

The library supports the following devices:
* DS3231, DS3232 RTC chips
* Piezo buzzer audio output
* Analog buttons
* Nixie Tubes (any: IN-14, IN-12, etc. )
* GL 5528 lightsensor (most popular light sensor on Arduino platforms)
* K155ID1 nixie drivers
* Mono-LEDs
* RGB-LEDs (both PWM controlled and Software controlled)
* LM35DZ temperature sensor

The library supports the following features:

* Switching between states (state-machine tasks)
* Sending and processing events
* * System events: timers
* * User defined events
* Fast analog read functions (optimized for Atmega328p)
* Fast digital write functions (optimized for Atmega328p)
