Pico Simon

A Simon Game implementation for the Raspberry Pi Pico.

Features

• Includes 3 games:
  • The classic simon game.
  • Catch me!, where lights start blinking and the player need to follow them without falling behind (with a margin).
  • Quick draw, multiplayer, when the lights turn on, the first one to hit the button wins.
• Settings for the games where you can choose:
  • from 3 leves of difficulty,
  • playing only with lights, only with sound or with both.

How does the menu works

• Red button: Simon
• Blue button: Catch me!
• Yellow button: Quick draw
• Green button: Settings
  • Red: Difficulty
    • Red: easy
    • Blue: medium
    • Yellow: hard
    • Green: back
  • Blue: Sound/Leds
    • Red: both
    • Blue: only Leds
    • Yellow: only sound
    • Green: back
  • Yellow/Green: back

To compile

There is a CMakeLists.txt file to build the project. You should also have set up the pico C SDK and CMake installed.

mkdir build
cd build
cmake ..
make

Circuit

I use 220 Ohm resistors, but you can switch those according to your LEDs.

The piezo speaker goes to a different ground pin because if I used the same, it caught some noise when using PWM to control the LEDs.

The buttons are pulled down by the pico.
