# 🏺 Kiln Maestro: ESP32-Based Professional Kiln Controller

A feature-rich, child-friendly kiln controller built on the ESP32 using FreeRTOS. This system manages high-temperature firing profiles (Bisque, Glaze, Custom) with real-time graph visualization.

🚀 Key Features

• Multithreaded Architecture: Powered by FreeRTOS for simultaneous sensing, control, and UI rendering.
• Dynamic UI: 2.4" TFT display with alternating Big Temp and Real-time Graph views.
• Child-Friendly UX: Simplified IR remote navigation with ±10/±100 increment controls.
• Safety First: Includes a software extrapolation layer for ADC saturation and EMA filtering for signal stability.

🛠️ Hardware Stack

• MCU: ESP32 (NodeMCU-32S)
• Display: ILI9341 2.4" TFT
• Sensor: K-Type Thermocouple with custom Op-Amp amplification
• Input: NEC IR Remote (HX1838)

📁 Project Structure

• /src: Core logic, FreeRTOS tasks, and UI state machine.
• /include: Header definitions and configuration.
• platformio.ini: Project dependencies and build flags.
