Snooze Button for Blues Wireless Notecard Alerts

The Notecard is great at generating alerts. How about a Snooze Button to pause those alerts until you've had a chance to deal with them?

Programatic Interaction

C/C++
The Arduino compatible code detailing how to interact with the Soft Snooze Button.
#define SOFT_SNOOZE_PIN 5 // Replace `5` with the pin connected to the yellow wire.

// Check the pin status
::pinMode(SOFT_SNOOZE_PIN, INPUT);
bool snooze_state = ::digitalRead(SOFT_SNOOZE_PIN);
// If snooze_state is true, then SNOOZE state has been previously set (as shown below).
// If snooze_state is false, then SNOOZE state has never been set, or the physical
// button has been pressed to reset the state.


// Set the pin into SNOOZE state
::pinMode(SOFT_SNOOZE_PIN, OUTPUT);
::digitalWrite(SOFT_SNOOZE_PIN, HIGH);
::delay(1);
::digitalWrite(SOFT_SNOOZE_PIN, LOW);
// As long as the soft snooze button remains powered, it will stay in the SNOOZE
// state (regardless of the MCU behavior), until the physical button is pressed.
