Arduino Spy Bug

A simple voice recorder for Arduino using an SD card and an electret microphone amplifier circuit.

Independent of any 3rd party libraries (unless delayed recording is used).

Wiring (also documented in spybug/spybug.ino)

SD Card Wiring

SD Nano
D0 (DO) D12 (MISO)
VSS GND
CLK D13 (SCK)
VDD 5V or 3V3
CMD (DI) D11 (MOSI)
D3 (CS) D10 (SS)

WARNING: SD cards are not designed for 5V; I have been using 5V anyways and everything seems fine, but beware that there is a significant risk of immediate or premature failure when not using a buffer circuit.

SD pin D3 is the chip select pin. It can be set manually in PIN_SS.

Microphone Wiring (MAX9814 w/ electret microphone)

Mic Nano
VCC 5V
GND GND
Out A0

Out defaults to A0 (AdcChannel0), but can be set manually in ADC_CHANNEL.
