// #define TURN_PERIPHERALS_OFF // Uncomment this line to turn off the peripherals before going to sleep
#define SLEEP_PIN D0 // Pin used to put the device to sleep
#define WAKE_PIN A3 // Pin used to wake up the device

/*
The following pins can be used to wake up the device: A0, A1, A2, A3, A4, A5, D4, D7
However turnPeripheralsOff() in this sketch turns off the power lane of the analog pins.
This means they cannot sink current and therefore cannot be used to wake up the device.
Hency only D4 and D7 can be used to wake up the device in this configuration.
