闲来无事做了一个电子色子, 和女儿一起玩飞行棋.
所需材料如下:
1. arduino pro mini 一块
2. 倾斜开关 一个
3. 蜂鸣器 一个
4. ws2812 LED灯 九颗
[mw_shl_code=cpp,true]
#include <FastLED.h>
//LED数量
#define NUM_LEDS 9
//ws2812的数据针脚
#define PIN 6
//蜂鸣器针脚
#define BeepPin 4
//倾斜开关针脚
#define inPin 9
CRGB leds[NUM_LEDS];
CRGB Dice[6][9]={{CRGB::Black,CRGB::Black,CRGB::Black,CRGB::Black,CRGB::Red,CRGB::Black,CRGB::Black,CRGB::Black,CRGB::Black},

楼主
感激不尽 我是高中学生 有通技课作业 自己看不懂代码 ...靠4张图好像无法完成这个项目，您能稍微给点补充提示啊或者其他的图片之类的吗？谢谢了，抱歉您在百忙之中还要抽空来回答
