/*
Radical EcoSystem — Moisture Threshold Patch

Author: Carlotta Premazzi
Program: Fabricademy 2025/2026
System Type: Bio-Hybrid Installation

Description:
This patch reads soil moisture values from an analog sensor and classifies them
into three environmental states: DRY, OK, and WET.

Two thresholds define the system:
- dryThreshold → above this value, the system is considered DRY
- wetThreshold → below this value, the system is considered WET
- values in between define the OK state

The current state and raw sensor value are printed to the Serial Monitor,
allowing calibration and real-time observation of environmental conditions.

This simple logic forms the base layer for behaviour in the installation.
