+# 🌡️ ThermoMood Display
+
+**A circular mood visualizer based on skin temperature — perfect for your desk or cubicle.**  
+Touch the thermocouple, and the GC9A01A round display reveals a mood with color and snarky commentary.
+
+---
+
+## 📦 Features
+
+- Displays Fahrenheit temperature at the bottom of a circular screen
+- Mood is selected based on skin temperature ranges
+- Background color changes dynamically with mood
+- Funny, sarcastic, cubicle-safe mood labels
+- Word-wrapped, auto-centered text
+- Smooth average filtering to avoid noisy updates
+

+
+## 🛠️ Hardware Requirements
+
+| Component | Details |

+| **Converter Module** | MAX6675 Thermocouple Amplifier |
+| **Wiring** | 4-Wire SPI (Display) + 3-Wire SPI (MAX6675) |
+
+---
+
+## 📷 Pinout (Example Wiring)
+
+| Signal | Arduino Nano ESP32 | Module |
+|--------|--------------------|--------|
+| **SO** (Thermocouple) | `D4` | MAX6675 SO |
+| **CS** (Thermocouple) | `D5` | MAX6675 CS |
+| **SCK** | `D6` | MAX6675 SCK |
+| **TFT DC** | `D7` | GC9A01A DC |
+| **TFT CS** | `D10` | GC9A01A CS |
+| **TFT RST** | `D8` | GC9A01A RST |
+| **TFT SCK/MOSI** | Default SPI | GC9A01A SCK/MOSI |

+
+## 🎨 Mood Mapping (Temperature → Mood)
+
+| Temp Range (°F) | Example Moods |
+|-----------------|----------------|
+| `< 85` | "Are you even alive?", "CRASHING OUT" |
+| `85–87` | "Quietly spiraling", "Flatline on enthusiasm" |
+| `88–89` | "Classic cubicle-core", "Emotionally beige" |
+| `90–91` | "Deadline panic", "Running on fumes" |
+| `92–93` | "Unraveling", "Caffeinated and dangerous" |
+| `94–95` | "TIME FOR YOU TO GO HOME", "Corporate martyr detected" |
+| `> 96` | "Go touch grass", "Return to sender (overheated)" |
+
+---
+
+## 💻 Libraries Required
+
+Install these via the Arduino Library Manager:
+
+- `Adafruit_GFX`
+- `Adafruit_GC9A01A`
+- `MAX6675` (Adafruit version recommended)
+
+---
+
+## 🚀 To Run
+
+1. Wire up your components as listed.
+2. Upload `ThermoMood_Display.ino` using Arduino IDE (board: **Arduino Nano ESP32**).
+3. Touch the thermocouple — your mood will appear!
