ASR M08-B設置軟件 V3.2 arduino 2560+ASRM08-B測試程序 arduino UNO+ASRM08-B測試程序語音控制臺燈電路圖及C51源碼(不帶校驗碼) 繼電器模塊設置。 ASR M08-B是一款語音識別模塊。首先對模塊添加一些關鍵字，對著該模塊說出關鍵字，串口會返回三位的數，如果是返回特定的三位數字，還會引起ASR M08-B的相關引腳電平的變化。【測試】①打開“ASR M08-B設置軟件 V3.2.exe”。②選擇“串口號”、“打開串口”、點選“十六進制顯示”。③將USB轉串口模塊連接到語音識別模塊上。接線方法如下：語音模塊TXD --> USB模塊RXD語音模塊RXD --> USB模塊TXD語音模塊GND --> USB模塊GND語音模塊3V3 --> USB模塊3V3（此端為3.3V電源供電端。）④將模塊的開關撥到“A”端，最好再按一次上面的大按鈕（按一次即可，為了確保模塊工作在正確的模式）。⑤對著模塊說“開燈”、“關燈”模塊會返回“0B”、“0A”，表示正常(注意：0B對應返回值010，0B對應返回值010，返回是16進制顯示的嘛，設置的時候是10進制設置的)。
