/*
Analog input, LCD output
Reads an analog input pin, prints the results to the LCD dislay(16x2)
The circuit:
* A-out of Analog/digital Soil moisture sensor is connected to analog pin A5.
+5V and GND of the Soil moisture is connected to the respective pins of Arduino.
* LCD Shield/LCD display is connected according to the connections mentioned.
