Is the LCD and i2c pre-soldered?

This assembly is completely assembled and ready to used with the I2C interface

What library should you use for python on a Raspberry Pi and where can we download said library?

You use the smbus (import smbus} The Internet will show how to get this. Here's a start for your code (much reading to do online to show something on the display, including the necessary voltage level transformation circuit for going from the 3.3 volt R-pi to the 5 volt display): # Interface Raspberry Pi to 16x2 i2c lcd display import RPi.GPIO as GPIO import sys import smbus import time # lcd address (verfiy using Linux command sudo i2cdetect -y 1) addr = 0x27 #Open i2c from smbus bus = smbus.SMBus(1) #much additional code needed, but there are numerous Internet resources

Will this work with the arduino?

Yes this works well with Arduino using the I2C library.
