能說說你的“激光豎琴”工作原理碼？

從你說的情況看，你是不是只有七根激光弦？所以才要高中低單調(diào)調(diào)節(jié)。
由于不知道你的程序、硬件是什么樣的，也不好多說什么。
只說一點(diǎn)：音樂上的頻率表，其實(shí)你自己也是查得到的。
音階頻率表
音階    Octave0 Octave1  Octave2  Octave3
Do  C    262    523    1047    2093
Db    277    554 1109    2217
Re  D    294    587    1175    2349
Eb    311    622    1245    2489
Mi  E    330    659    1329    2637
Fa F    349    698    1397    2794
Gb    370    740    1480    2960
Sol  G    392    784    1568 3136
Ab    415    831 1661    3322
La  A    440    880    1760    3520
Bb    466    923 1865    3729
Si B    494    988    1976    3951
根據(jù)這個(gè)頻率表，設(shè)計(jì)和編程，當(dāng)然，至少還得加一個(gè)按鍵什么的，就可以讓你的七弦，變成N弦了

通過對(duì)光敏電阻阻值的改變，用單片機(jī)產(chǎn)生不同的頻率，發(fā)出音樂的7種音調(diào)
