 ====Introduction====
 <nowiki>
-The True Random Number Generator (TRNG) project utilizes an Arduino Uno, LEDs, a microphone, and capacitors to generate unbiased and unpredictable random numbers based on ambient noise. By capturing noise signals with the microphone and using them to seed the Arduino's random number generator, the project provides a practical solution for generating true randomness with visual feedback through blinking LEDs.
+Introducing the Dice Game with Temperature Sensor! This interactive project combines the excitement of a dice game with the unpredictability of temperature fluctuations. By integrating a DHT temperature sensor, each roll of the dice is influenced by the current temperature reading. As you press the button, LEDs flicker, a buzzer plays a slot-like melody, and the dice display a number affected by the temperature, offering a unique and immersive gaming experience. Let the temperature shape your luck and add a new dimension to your gaming adventures!

 ====General Description====
 <nowiki>
-The True Random Number Generator (TRNG) project utilizes an Arduino Uno board, LEDs, a microphone, and capacitors to create a device that generates random numbers based on ambient noise. The project taps into the inherent variability in noise signals to produce unbiased and unpredictable random numbers, which have applications in cryptography, gaming, simulations, and other domains requiring random data.
+The Dice Game with Temperature Sensor is an intriguing project that combines the excitement of a dice game with the concept of true random number generation. Unlike traditional dice games that rely on predictable outcomes, this project introduces a temperature sensor to add a touch of unpredictability. The temperature reading influences the generated number, making it more akin to true randomness. By incorporating the ambient temperature into the randomization process, the project mimics the characteristics of natural random events, similar to true random number generators used in various applications. This unique feature brings an element of surprise and authenticity to the game, providing players with a more immersive and engaging experience. Whether it's a casual game among friends or an exploration of random number generation, this project offers an exciting blend of electronics, chance, and scientific principles.
-The Arduino Uno serves as the control unit, providing the necessary processing power and I/O capabilities. The microphone captures ambient sound signals, which contain random fluctuations. These signals are used to seed the Arduino's random number generator, ensuring the generated numbers are truly random.
-Visual feedback is provided through LEDs connected to the Arduino board, blinking briefly whenever a new random number is generated. Capacitors may be utilized for noise filtering, signal conditioning, or biasing purposes.
-The TRNG project combines the Arduino platform's flexibility with ambient noise sources to offer a practical and accessible solution for generating random numbers with high entropy.

 ===== Software Design =====
 == Libraries used ==
-  *<Wire.h>
+  *<DTH.h>
-  *<LiquidCrystal_I2C.h>
 == Funcții implementate: ==
-  * **void setup()**:
+  ***setup():** This function is called once at the beginning of the program and is responsible for initializing the pins and sensors.
-    * Declare the pins
+  ***generateRandomNumber():** This function reads the temperature from the sensor and generates a random number based on the temperature value. It combines the temperature reading with the traditional random number generation to add an element of unpredictability.
-    * Initialize the LCD display
+  ***playSlotSound():** This function plays a slot machine-like sound effect using the buzzer. It utilizes predefined arrays of notes and durations to create the desired sound.
-    * Display the initial text ("Press the button")
+  ***flickerLEDs():** This function controls the LEDs connected to the dice pins and makes them flicker rapidly, creating an animated effect during the dice roll.
+  ***loop():** This function is the main execution loop of the program. It continuously checks if the button is pressed and performs the dice roll sequence, including playing the sound, flickering the LEDs, generating the random number, and displaying it on the dice LEDs.
-  * **void loop()**:
-    * Verify if the button has been pressed
-    * If the button has been pressed the Buzzer starts and makes a noise every second for 5 seconds
-    * The LCD displays that the sensor is reading
-    * After 5 seconds the buzzer stops
-    * The code computes the average value read by the sensor
-    * The condition blocks inside the code verify the value and display the appropriate message
