How to Make Simon Memory Game Using Arduino | Simon Says Game

Summary

In this tutorial, we demonstrate how to build a Memory Game using Arduino. The video walks through the necessary components, including an Arduino UNO, 16×2 LCD, push buttons, LEDs, and a buzzer. We cover the setup and simulation in Proteus, followed by an in-depth explanation of the code, game logic, and hardware setup. Viewers will learn how to program the Arduino to create a game where the user must match LED sequences to progress through levels. The tutorial also covers troubleshooting, uploading the code, and customizing the game to run without the LCD display.

Takeaways

• 😀 The project demonstrates how to build a Memory Game using Arduino UNO, an LCD with I2C module, LEDs, push buttons, and a buzzer.
• 😀 The game’s goal is to memorize LED sequences and press the corresponding buttons to progress through levels.
• 😀 The setup includes Arduino UNO, a 16×2 LCD, four LEDs (Red, Yellow, Green, Blue), four push buttons, and a buzzer for sound effects.
• 😀 The circuit uses a 9V battery for power, with LEDs connected to Arduino pins and 100-ohm resistors in series to limit current.
• 😀 Push buttons are connected between Arduino pins and ground, while the buzzer is used to produce sound corresponding to LED colors.
• 😀 The simulation is run using Proteus, where the compiled Arduino code and circuit diagram are integrated.
• 😀 The code includes arrays for LEDs and buttons, with random LED sequences generated for each level, which the player must memorize.
• 😀 The game has multiple levels, with the LED sequence length increasing with each successful level completion.
• 😀 If the player presses the wrong button, the game displays 'you lost' and resets to the starting point.
• 😀 The game can be restarted at any point by pressing the red button, which resets the game to level 1.
• 😀 The buzzer's frequency changes based on the LED color, providing auditory feedback corresponding to each color/button pair.

Q & A

What is the main purpose of the project described in the video?

The main purpose of the project is to build a memory game using Arduino, where players must memorize a sequence of LED lights and press corresponding buttons to progress through levels.

Which components are used in the hardware setup for the memory game?

The hardware setup uses an Arduino UNO, a 16x2 LCD with an I2C module, four LEDs (red, yellow, green, blue), four push buttons, a buzzer, and a 9V battery for power.

How does the game start and progress through levels?

The game starts by pressing the red button. The game then displays the current level and status on the LCD. LEDs blink in a random sequence, and the player has to press the corresponding buttons to progress to the next level. The difficulty increases with each level as the number of LEDs to memorize increases.

What happens if the player presses the wrong button?

If the player presses the wrong button during a level, the game will display 'You loss' on the LCD and the game will end. The player can then press the red button to restart the game from level 1.

What does the code include in terms of game logic?

The code includes logic for generating random LED sequences, verifying if the player's button presses match the sequence, and progressing through the game’s stages. It also handles the LCD display, buzzer frequencies, and managing game levels and states.

What is the purpose of the buzzer in the memory game?

The buzzer is used to give audible feedback. Each LED/button combination has a distinct beep frequency, helping the player identify which button to press based on the LED light that is lit.

How is the random LED sequence generated in the code?

The code generates a random number between 8 and 11, which corresponds to the LED pin. This random sequence is stored in an array, and the LEDs blink according to the sequence for the player to memorize.

What happens after a player successfully completes a level?

When a player successfully completes a level, they are shown the 'you win' message on the LCD, and the game proceeds to the next level, which adds another LED to the sequence. The game continues until the maximum level is reached, at which point 'Congratulations' is displayed.

Can the memory game be played without the LCD?

Yes, the game can be played without the LCD. The same code can be used, but the LCD functionality would be omitted, relying only on LEDs and the buzzer for feedback.

What are the key variables initialized in the code for the game?

The key variables in the code include those for storing the button pins, LED pins, buzzer pin, random sequences for the LEDs, game level, and the player's inputs. Arrays are used to store the LED and button sequences for each stage.
