MicroMaker                                         版主                     2016-12-18 11:12                                                                                                                                                4917                                                                                                                                                                                                     本帖最后由 MicroMaker 于 2017-5-14 09:32 编辑        这个盒子可以不用按按钮就可以发出美妙的音乐。只要将手放在盒子上上下摆舞几下，你的耳朵里就会响起优美的音符，随着优美的音符响起，发出迷幻的光线，好像一个看不到底的时空隧道。                                                           它的原理是：打开开关，将手放置于超声波传感器上方，如果探测到在一个范围内，喇叭就发出一个音调；探测到在另一个范围内，喇叭就会发出另一个音调。同时，不同的LED发出不同的色彩。光线在镜子与单透膜之间无限反射，形成无数个影子。 整个小制作，分成五个部分： 第一部分： 先用超声波传感器测量超声波碰到手再返回的时间。 第二部分： 由主芯片发出不同频率的脉冲，使喇叭发出各种各样的音调。 音符（共11个）：a3;b3;c4;d4;e4;f4;g4;a4;b4;c5;d5; 第三部分： 利用不同的ＲGＢ颜色配比，形成由30个LED组成的光带，用一面镜子做底板，单透膜作为面板，LED光带放在镜子和单透膜之间，光线在镜子和单透膜之间无限反射，形成许多光带的影子。 第四部分： Arduino主芯片收到信息后，用公式计算出手与传感器之间的距离（公式：距离=时间*音速（340米/秒）/2）。按照不同的距离，主芯片命令发出不同的音乐、不同的LED发出不同的光。比如：距离为130mm，喇叭发出la(c)，第1、2、3、27、28、29号LED点亮。    第五部分：开发系统、开发板     本小制作采用了Arduino UNO开发板     主控芯片：ATMEGA 328p     编程软件为Arduino IDE     编程语言:C/C++ 主要元件目录表： 1.Arduino uno主板（1块） 2.us-100超声波模块（1块） 3.喇叭（1只） 4.30个LED组成的光环（1条） 5.11.1V电池组（1块） 6.电源降压模块（1块） 7.发光按钮开关（1个） 8.镜子（1面） 9.有机玻璃外壳（外贴单透膜）              超声波传感器               Arduino Uno单片机                        喇叭                      LED光带、镜子                    单透膜                  有机玻璃外壳       组装过程：        组装（1）                         组装（2）         组装（3）                          组装（4）           我去年用这个作品还获得过绍兴市第二季校园科学达人的称号呢！ 作品程序： [C++] 纯文本查看 复制代码 代码 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 071 072 073 074 075 076 077 078 079 080 081 082 083 084 085 086 087 088 089 090 091 092 093 094 095 096 097 098 099 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595 596 597 598 599 600 601 602 603 604 605 606 607 608 609 610 611 612 613 614 615 616 617 618 619 620 #include <Adafruit_NeoPixel.h>   //彩色LED库 # define PIN 6   //设置LED端口 # define MAX_LED 30    //特定的程序，最后一个数字是LED光带中LED的数量 Adafruit_NeoPixel strip = Adafruit_NeoPixel( MAX_LED, PIN, NEO_RGB + NEO_KHZ800 );  //彩色LED库的内部设置 int a = 2;// 将Arduino 的Pin2 连接至US-100 的Echo/RX int b = 3;// 将Arduino 的Pin3 连接至US-100 的Trig/TX void setup() { pinMode(a,INPUT);// 设置a 为输入模式。 pinMode(b,OUTPUT);// 设置b 为输出模式。 strip.begin();   //启动LED函数库  strip.show();   //将所有的LED灯灭掉 } void loop() { long c = 0;//脉冲时间 long d = 0;//脉冲距离 // 通过Trig/Pin 发送脉冲，触发US-100 测距 digitalWrite(b,LOW);
