Arduino UNO: Temperature over LCD

In this project we are going to use a temperature sensor in order to read its value and displaying on a LCD screen.

We connected two potentiometer in order to adjust LCD backlight and contrast as well.

After sketch loading completed, your board will display current temperature, but only after computing an average of 100 samples read from temperature sensor. This to avoid crazy reading data every cycle.
