We can use soil moisture sensor with arduino nano and show data in a 2x16 lcd. Let's start...

Step 1: Add 2X16 LCD to Arduino Nano

RS=12

R/W=ground

ENABLE=11

LCD D4=9

LCD D5=8

LCD D6=7

LCD D7=6

You can see other connections in the picture.

Step 2: Add Soil Moisture Sensor

It is very easy..There are 3 pins to connect arduino nano.

VCC----> +5 volt

GND---->GND
