  "section0IntroMarkdown": "## 🌱 Welcome to the Arduino plant workshop!\nToday we will learn how to build an automatic watering system with Arduino. Using this microcontroller, we will read a moisture sensor and control a pump so that our plants get water at exactly the right time.\n\n**What you will learn:**\n- How to read sensors (measure moisture in the soil)\n- How to control electrical devices (switch pump on/off)\n- How to combine both parts (automatic watering)\n\n> **Note:** We are using Arduino, a platform that makes it easy to control hardware with code. No worries if you have never programmed before — we start from the very beginning! You can choose between a beginner mode with drag-and-drop code blocks and an advanced mode where you fill in code gaps yourself.",
  "section0SafetyMarkdown": "### Safety notes\n- **Water and electricity:** Make sure no electrical parts (except the sensor) come into contact with water.\n- **Power supply:** Use only the provided power supplies and voltage levels.\n- **If you have problems or are unsure:** Always ask for help.",
  "section1PowerWarningMarkdown": "> **⚠️ IMPORTANT SAFETY RULE:** Never switch on power without a supervisor! The power supply may only be activated together with a supervising adult."
