With to a greater extent than than eleven minutes of recording room, you lot tin create anything from recording cool well bites using the PC to cool Arduino projects such every bit phonation activated doorbells, warning systems, etc.
The HQ Audio module features a microcontroller, an external well input, onboard microphone, 8 momentary force buttons, record/playback switch, well output (to plug inwards a gear upward of speakers), speaker connexion and a pivot runway to connect your Arduino.
The module board tin play 1 genuinely long message or upward to 8 unlike messages via 4 modes of operation: unmarried message mode, 2 message mode, 4 message trend as well as viii message mode.
You snuff it 2 ability options onboard also, which include a 5mm ability socket (for an ac to dc adapter) as well as ability final block amongst V+ (from 7.5volts to 12 volts) as well as Ground for the DC ground.
Interfacing the HQ module board amongst your Arduino is done via the module's 10-pin header. Two of these pins are the v+ (regulated five volts) as well as DC set down connection. The other viii pins check to the 8 force buttons as well as these pins command messages 1 through viii respectively.
It is real tardily interfacing the HQ Audio module amongst Arduino every bit you lot only execute a digitalWrite GPIO HIGH telephone outcry upward yesteryear default of all the GPIOS from your Arduino that are connected to whatsoever of these pins. To tape or playback messages, you lot execute a digitalWrite GPIO LOW telephone outcry upward (you only remove a 100 ms depression pulse to trigger a playback). To halt playback, you lot only mail about other depression pulse during mid-message to cancel the playback as well as provide to standby mode.
