由于是自己探索，基本刚刚起步学习，算是基本没有学过系统的知识，而且时间比较紧迫，有些问题实在没办法解决，希望能得到大家的帮助，谢谢！
首先，在用arduino驱动的光立方中能不能不使用电阻？ 其次，我在一个视频中看到他利用了三极管做每层的开关，请问这个是必要的吗，而且这些开关起到什么作用？ 最后，请问能不能帮我讲解一些下面的代码各部分的具体含义和效果功能。 再次感谢！ #include #define XAXIS 0 #define YAXIS 1 #define ZAXIS 2 #define POS_X 0 #define NEG_X 1 #define POS_Z 2 #define NEG_Z 3 #define POS_Y 4 #define NEG_Y 5 #define BUTTON_PIN 8 #define RED_LED 5 #define GREEN_LED 7 #define TOTAL_EFFECTS 8 #define RAIN 0 #define PLANE_BOING 1 #define SEND_VOXELS 2 #define WOOP_WOOP 3 #define CUBE_JUMP 4 #define GLOW 5 #define TEXT 6 #define LIT 7 #define RAIN_tiME 260 #define PLANE_BOING_TIME 220 #define SEND_VOXELS_TIME 140 #define WOOP_WOOP_TIME 350 #define CUBE_JUMP_TIME 200 #define GLOW_TIME 8 #define TEXT_TIME 300 #define CLOCK_TIME 500 #define REMAIN_TIME 25000 //uint8_t characters[10][8] = { // {0x3C, 0x42, 0x42, 0x42, 0x42, 0x42, 0x42, 0x3C}, //0 // {0x10, 0x18, 0x14, 0x10, 0x10, 0x10, 0x10, 0x3C}, //1 // {0x3C, 0x42, 0x40, 0x40, 0x3C, 0x02, 0x02, 0x7E}, //2 // {0x3C, 0x40, 0x40, 0x3C, 0x40, 0x40, 0x42, 0x3C}, //3 // {0x22, 0x22, 0x22, 0x22, 0x7E, 0x20, 0x20, 0x20}, //4 // {0x7E, 0x02, 0x02, 0x3E, 0x40, 0x40, 0x42, 0x3C}, //5 // {0x3C, 0x02, 0x02, 0x3E, 0x42, 0x42, 0x42, 0x3C}, //6 // {0x3C, 0x40, 0x40, 0x40, 0x40, 0x40, 0x40, 0x40}, //7 // {0x3C, 0x42, 0x42, 0x3C, 0x42, 0x42, 0x42, 0x3C}, //8 // {0x3C, 0x42, 0x42, 0x42, 0x3C, 0x40, 0x40, 0x3C}, //9 //};
