# 🌱 Water-to-Earn DIY Project

Turn watering your plants into token rewards using:

• ESP32 soil moisture sensor
• Node.js backend with ethers.js
• ERC20-like Solidity smart contract
• Minimal frontend dashboard

Project Structure

• firmware/: ESP32 Arduino sketch
• backend/: Node.js backend (Render deployable)
• contract/: Solidity PLNT token contract
• frontend/: Dashboard (GitHub Pages deployable)

Instructions

1. Flash the ESP32 with firmware/plant_to_earn.ino
2. Deploy contract/PlantToken.sol to Polygon Mumbai (e.g., using Remix)
3. Deploy backend to Render (use .env.example to create your .env)
4. Deploy frontend on GitHub Pages (static hosting)
5. Water your plant and earn tokens!
