 ====Introduction====
 <nowiki>
-This alcohol tester provides a convenient and portable solution for individuals to monitor their alcohol consumption levels. It can be used for personal use or in situations where alcohol testing is required, such as safety checkpoints or professional settings.
+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 alcohol tester made with an Arduino Uno board, an MQ-3 sensor, a button,a buzzer, and an LCD display is a device designed to measure alcohol concentration levels. It provides a simple and convenient way to determine if an individual is sober, within legal limits, or drunk.
+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 MQ-3 sensor is used to detect the presence of alcohol in the surrounding environment. When the button is pressed, the device initiates a 5-second countdown.A buzzer produces a sound every second to signal the measurement period. The sensor readings taken during this time are then processed to calculate the average alcohol concentration.
-Instead of displaying the results on the serial monitor, an LCD display is used to provide a user-friendly output. The LCD screen is connected to the Arduino Uno board via an I2C module, which simplifies the connection and communication between the two.Once the sensor reading is complete, the calculated alcohol concentration value is displayed on the LCD. The display provides different messages based on the concentration level. If the concentration is below a predefined sober threshold, the LCD displays "Sober" along with the measured value. If the concentration is within the legal limit, it shows "Have been drinking" And if the concentration exceeds a predefined drunk threshold, it displays "Drunk" as an indication of intoxication.

 ===== 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
