NokiaLCD

Received my LCD from NOKIA 5110(or 3110 – can’t remember really)
and started to play with it.
I’ve used Adafruit’s libraries (they are awesome…).
For download from there-> https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library
local copy
though this one requires this one as well -> https://github.com/adafruit/Adafruit-GFX-Library
local copy
and below is effect of my HC-SR04 and this nifty LCD.

image developed using Fritzing.
