I have managed to get my ATMEGA328 working on a breadboard with LCD.
I have a LM35 hooked up too but is saying the tmp is 400C :-0,its not even hot, it would melt i guess.

The LM35 seems okay as i have tried them both on the Original Arduino
The output of the LM35 is 0.29V (29C) but the LCD siplay is saying 439C - 823F with the LM35 connected or or not connected :-S
Is LM35's ground connected to Arduino's ground.
Are you using the right anlogue input.
Post the code.
Leo..
I tried A1 + A2 nothing, it was connected to ground.
Might be the breadboard unsure.
Hi,
Check your breadboard/protoboard as some have the side supply rails disconnected in the middle.

No mine, is connected straight through. LM35 not on the Breadboard took picture when i took the LM35 OFF
See image.
Use a voltage divider, 100k from +5volt to pin23, 10k from pin 23 to ground.
Code should read Analogue pin 0.
You should get 45 degrees C, or 113 Fahrenheit on your LCD.
Better to have the power links between top rails and bottom rails near the supply/micro.
Not all the way at the end of the board.
