ESP32 Memory Game

A memory game created with an ESP32 and MPR121 in the Arduino IDE with C++

Materials Needed

• 6 LEDs
  • 1 Blue
  • 2 Green
  • 1 Yellow
  • 2 Red
• 6 220Ω Resistors
• 1 MPR121
• 1 ESP32
• Lots of Jumper Wires
• Aluminum Foil or Copper Foil Tape (for touchpads connected to MPR121)

Features

• Uses MPR121 for interactive touch detection
• LEDs for aesthetic feedback
• Touch feedback spam prevention
• Random sequences with <random> and <vector>

How to Use

#1 Install Arduino IDE

Download the IDE with this link: https://www.arduino.cc/en/software/

#2 Install necessary Board Support for ESP32

In the IDE, open Files > Preferences > Additional Board Manager URLs and paste this link: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

#3 Install Dependencies

Library Manager > Search Adafruit MPR121 > Install

#4 Clone this Repository

git clone https://github.com/CookieCodesAI/memory_game_esp32.git

#5 Open the memory_game.ino file in Arduino IDE

#6 Choose ESP32 board and port

• Tools > Board > Choose Board
• Tools > Port > Choose Port

#7 Upload the Code

Click the Upload button to upload code to ESP32

Additional Things

• Based on the sensitivity, users may have to adjust the threshold of the MPR121. Update this line of code based on the sensitivity of MPR121:

cap.setThresholds(0, 0);
