Story

Introduction

Press the switch once, generate a random number between 1 and 6, and display it on the LED display.

Description

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.
