Hello! I was wondering if there is any way to read the data given to a lcd by an atmega 328p.
I have a geiger radiation kit that comes with a lcd controlled by an atmega.
My question is simple: Is there any way I can display the data given to the lcd, on serial monitor using my arduino? 
What sort of interface (how many wires would be a clue) are there between the 328 and the LCD ?
And if the display is working, what is the reason for wanting to 'read' the data being sent to the display ?
I guess OP wants to read the value with another Arduino.
There are bound to be easier ways. If it's an open source kit it's probably quite easy to reprogram the thing so the values are made available on the Serial interface (and hope you can connect to those pins).
