Objective:

Learn to use the Soil Moisture Sensor to measure soil humidity levels and control RGB LED indicators based on moisture content, enabling automated plant watering systems.

Steps to Perform:

1. Click 'Start Simulation' to power the Arduino and enable the moisture sensor
2. Use the slider to adjust soil moisture levels from 0% (dry) to 100% (wet)
3. Observe the RGB LED color changes:
   • Red LED: Dry soil (0-39% moisture) - needs watering
   • Yellow LED: Moderate moisture (40-54% moisture) - optimal level
   • Green LED: High moisture (54-100% moisture) - overwatered
4. Monitor the moisture percentage displayed below the slider
5. Notice how the sensor reading maps to 0-255 Arduino analog values

Key Concepts:

• Soil Moisture Sensor: Measures soil water content using resistance between two probes
• Analog Reading: Arduino reads sensor values (0-1023) and maps to 0-255 range
• RGB LED Indication: Visual feedback system with three states (dry/moderate/wet)
• Threshold Logic: if-else conditions control LED based on moisture ranges
• Automated Irrigation: Can trigger water pumps when moisture drops below threshold
• Applications: Smart agriculture, garden automation, greenhouse monitoring
