# Smart Climate Control Dashboard

An integrated automation layout built on an Arduino Uno. The micro-controller polls ambient conditions from a DHT22 sensor element, displaying telemetry dynamically on an I2C SSD1306 OLED interface, while conditionally driving a DC Cooling Fan subsystem.

## Telemetry Pin Map

### DHT22 Sensor
* **VCC** ➡️ Arduino **5V** (Red Wire)
* **SDA** ➡️ Arduino **D4** (Green Wire)
* **GND** ➡️ Arduino **GND** (Black Wire)

### DC Motor (Fan Simulation)
* **IN1** ➡️ Arduino **D3** (Blue Wire)
* **GND** ➡️ Arduino **GND** (Black Wire)

### SSD1306 OLED Display (128x64 I2C)
* **VCC** ➡️ Arduino **5V** (Red Wire)
* **GND** ➡️ Arduino **GND** (Black Wire)
* **SDA** ➡️ Arduino **A4** (Orange Wire)
* **SCL** ➡️ Arduino **A5** (Yellow Wire)

## Execution and Calibration
1. Fire up the simulation engine by pressing **Start Simulation**.
2. Left-click directly onto the red **DHT22 Sensor block** inside the graphics grid to open the temperature/humidity slider tools.
3. Move the temperature indicator past **30.0°C**. Notice the status text on the OLED shift instantly to **RUNNING**, and look closely at the DC Motor element—it will begin spinning at high speed.
4. Drop the level down below **30.0°C** to verify the automation loop shuts down power to the fan.
