A Memory Game built on the Arduino Platform. Project made for TEJ4M

This project uses PlatformIO, and is designed for an Arduino UNO. The libraries that this project depends on are included in the platformio.ini file. Simply connect your Arduino, and upload the script with PIO.
Required Components:
- 1x I2C (or compatible) LCD
- 1x 10K Ohm Potentiometer
- 1x Push Button
- 1x 10K Ohm Resistor (for the button)
Optional Components:
- 1x Piezo Buzzer
- 1x 100 Ohm Resistor (for the buzzer)
The game is based on the generic card matching memory game. I decided to replicate this game due to its simplicity, but also because it is fun to play. The basic premise of the game is to pick matching cards out of a set of unknown cards. Once the player picks all matching pairs, they win the game.
The player will interact with the game with a Potentiometer (As a joystick) and a button to select the letter.
- First I designed the game on Wokwi (See the online demo for this)
- I transferred the design onto a physical breadboard.
I wanted the game to handle input, render the pixels on the screen, count down the time remaining, and to run other tasks at the same time. This is why I decided enlist the help of the Task Scheduler Library. With the use of this library, I am able to schedule tasks with relative precision.
| Problem | Attempted Solution | Resolution |
|---|---|---|
| LCD display does not output correctly | Tried re-connecting the wires | Found that the I2C interface required a special library |
| Task Scheduler not running properly | Tried re-creating the tasks (Game tick task, render task, input scan task, etc) | Found out that I double-initialized the task scheduler. |
| The potentiometer was not inputting on a linear scale | Tried with a different potentiometer | Resolved the problem by manually correcting the non-linear input. |
| LCD Display has poor refresh rate | N/A | Refrained from clearing the display. Instead, I overrode the existing pixels. This effectively doubled the refresh rate |
I am not very experienced in electronics, so take these instructions as general recommendations. I highly recommend you to first do some googling around before trying this.
