An Arduino library for driving the monochrome Nokia 5110 LCD. It has a rather small footprint and is therefore able to run on many ATTiny microcontrollers.

There are many nice libraries for the inexpensive Nokia 5110 display out there which are probably more feature-complete. The main advantage of this one is using neither a framebuffer nor the SPI library. As a result it is lightweight enough and keeps dependencies to a minimum, thus suitable to run on various Arduino-compatible microcontrollers.

The library should be simple to use and the API is well documented. Demo sketches can be found in the examples/ directory. To start using this library, install it manually or look it up in the library manager of your Arduino IDE.
