Color Memory Game
|
||||
=================
|
||||
|
||||
This is a memory game (with pairs of cards), played on a WS2812B RGB LED strip.
|
||||
|
||||
The code is designed for *Arduino Pro Mini* (16 MHz), and can be flashed with avrdude (use the Makefile) using a USB-to-serial adapter.
|
||||
|
||||
Peripherals
|
||||
-----------
|
||||
|
||||
- WS2812B RGB LED strip (or chained pixels) for the game board
|
||||
- 4 buttons for navigation (arrows)
|
||||
- 2 buttons for RESTART and SELECT
|
||||
|
||||
The LED strip should have a large capacitor (~ 1000uF) in parallel to the power supply, to avoid flickering.
|
||||
|
||||
It's connected over a resistor (470R will do fine) to the Arduino.
|
||||
|
||||
All pins can be adjusted in the `main.c` near the top, also the board size can be changed (for more than 15 card pairs, you'll have to add more colors).
|
||||
|
||||
Board
|
||||
-----
|
||||
|
||||
The LEDs are numbered in this manner:
|
||||
|
||||
0 1 2 3
|
||||
4 5 6 7
|
||||
8 9 10 11
|
||||
12 13 14 15
|
||||
|
||||
Set the board width and height in `main.c` to match your setup.

MightyPorsk's AVR utils library
|
||||
===============================
|
||||
|
||||
This is my ever-evolving library. When I'm done with a project, I copy the current library to the project, so it doesn't break when I do further improvements.
|
||||
|

Each library file contains a large comment block explaining it's function.

- io2n() provides pin number.
