Circuit Setup

Connecting the Soil Moisture Sensor to Arduino Mega:

Instructions

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud).

Observe the moisture level percentage readings.

Dip the sensor in water to see the percentage increase, and let it dry to see it decrease.
