$ cat features.txt

- potentiometer
                        input
    smooth steering with analog input

- dedicated
                        buttons
    gas and brake pedal simulation

- LCD display
                        feedback
    real-time speed, direction, factor

$ cat components.txt

- arduino
                        uno
    main microcontroller

- potentiometer
    10kΩ linear for steering

- push buttons
                        (x2)
    tactile switches for gas/brake

- LCD display with
                        I2C
    1602A + I2C converter

$ cat how_it_works.txt

Raw input values from the board are formatted
and sent over serial connection to computer.

Communication: /dev/ttyUSB0 @ 9600 baud
Game listens for data, parses received string
and updates car movement accordingly.

// Pin Configuration
Buttons: pin 2 and 3 (digital input)
LCD: A4 (SDA), A5 (SCL) for I2C
Potentiometer: A0 (analog input)

$ cat TODO.md

[ ] custom driver
    make a real controller out of it (??)

[ ] improve the game
    from 2D to 3D graphics
    better movement physics

[ ] add acceleration
    smooth movement on steering
    force feedback simulation
