4. Usage The speaker can emit a variety of sounds like a car horn, doorbell and ignition. The different sounds are based on the frequency of the input signal. You can supply different frequency signal to this module with Arduino. Arduino generates these signal via PWM or even digital write and delay. - Page 9 void pinInit() pinMode(SPEAKER,OUTPUT); digitalWrite(SPEAKER,LOW); void sound(uint8_t note_index) for(int i=0;i<100;i++) digitalWrite(SPEAKER,HIGH); delayMicroseconds(BassTab[note_index]); digitalWrite(SPEAKER,LOW); delayMicroseconds(BassTab[note_index]); Note: Due to the influence of the capacitance, the module can only output the bass signal, and the treble is unable to emit.
