 - Smart Automation: Includes automatic brightness scaling based on a set night-mode schedule.
 
+## Hardware Requirements
+- Microcontroller: ESP32 Development Board (e.g., ESP32 DevKit V1).
+
+- Display: 4-in-1 MAX7219 LED Matrix Module (or 4 individual 8x8 modules daisy-chained).
+
+- Wiring: Jumper wires (Female-to-Female typically used for the matrix connections).
+
+- Power: 5V Power Supply (Note: If using 4+ modules, it is highly recommended to power the matrix directly from a 5V source rather than the ESP32's 3.3V pin to prevent instability or brownouts).
+
 ## Wiring
 - DATA: GPIO 13
 - CS: GPIO 14
 - CLK: GPIO 15

+## Library Requirements
+To compile this project, the following libraries must be installed in your Arduino IDE (navigate to Sketch > Include Library > Manage Libraries... and search for these names):
+
+- MD_MAX72xx (by MajicDesigns): Handles the low-level LED matrix driver.
+
+- MD_Parola (Optional but recommended): Often used alongside MD_MAX72xx for easier text effects, though this project uses pure MD_MAX72xx.
+
+- NTPClient (by Fabrice Weinberg): Used to sync the time from the internet.
+
+- ArduinoJson (by Benoit Blanchon): Required to parse the JSON data returned by the OpenWeatherMap API.
