The link you provided to Adafruit describes different pins for LCD, than in the code. I wanted to build this, but it is not possible just following this instructable. Could be connection between Uno and LCD shared also?

So pcd-8544 are the same number for nokia 3310 and 5110 so it doesn't matter that either lcd came out of 3310 or 5110 ... am i right??

It's an oscilloscope, It reads changes in voltage, not data.

i thought it could read serial data, so I asked. By the way, how do I modify the code to suit a 100K potentiometer? Cuz I'm currently out of 10K potentiometers at the moment and I wanna do this quick.

The scope doesn't have a trigger at the moment, however, I did put a potentiometer on A1 to change the scanning speed of the scope, allowing you to look at faster waves.

What type of potentiometer did you use. Like a 10K ohm.
