<p>➀ This article introduces a soil moisture indicator designed for gardening applications, which uses an Arduino Nano and an LCD display to indicate the moisture level of the soil.</p><p>➁ The device categorizes soil moisture into four levels: dry, humid, wet, and 'sensor not in soil'. It provides a cost-effective solution for monitoring soil moisture with minimal human intervention.</p><p>➂ The project includes detailed instructions for building the indicator, including the necessary components like the Arduino Nano, Soil Moisture Sensor, and LCD I2C, along with the corresponding circuit diagram and source code.</p>
