<h3>Materials Needed:</h3><ul><li>1 x Arduino Uno board</li><li>7 x LEDs</li><li>7 x 220Ω resistors (one for each LED to limit the current flowing through the LED)</li><li>1 x Breadboard (optional, for easy connections)</li><li>Assorted jumper wires (for connecting components)</li></ul><h3>Connection Steps:</h3>Connecting LEDs and Resistors:<ul><li>Connect the long leg (anode) of each LED to a digital pin on the Arduino Uno ( pins 3, 4, 5, 6, 7, 8, 9).</li><li>Connect the short leg (cathode) of each LED through a220Ω resistor to the GND pin.</li></ul>Connecting Resistors to GND:<ul><li>The other end of each 220Ω resistor should be connected to the GND pin .</li></ul>Running Light Effects:The program implements several different LED display modes within the `loop()` function.Individual Lighting: First, the program lights up each LED individually, with each LED staying on for 100 milliseconds before turning off and moving on to the next LED.All On: Then, the program lights up all LEDs at the same time, maintaining this for 1 second.Individual Extinguishing: Next, the program turns off each LED individually, with each LED staying on for 100 milliseconds before extinguishing.Individual Blinking: Finally, each LED blinks on its own three times, staying on for 300 milliseconds each time, with a 300-millisecond interval between blinks.Loop Delay: After each mode ends, the program waits for 1 second before repeating the above modes, forming a loop.

The Dice Simulator is an interactive simulation project that mimics the rolling of a fair six-sided die using an Arduino UNO. In this project, a common cathode seven-segment display is used to visually represent the outcome of a dice roll, and a switch is used to initiate the simulation of a dice roll. When the switch is pressed, the Arduino UNO simulates the rolling of a dice by generating a random number between 1 and 6. This number is then displayed on the seven-segment display, providing a visual representation of the dice roll outcome. The Dice Simulator project is a simple yet effective way to demonstrate the use of random number generation in Arduino-based projects and can be expanded for various interactive applications, such as games or probability experiments.
