// This program assumes that:
//  1. An SPST switch connected between digital pin 2 and ground, and a 10K
//  pullup resistor between digital pin 2 and +5V.
//  2. The serial console on the Arduino IDE is set to 9600 baud communications speed.
// ================================================================================
// Define constant values.

// The wiring assignment.
#define SWITCH_PIN 2

// ================================================================================
// Configure the hardware once after booting up.  This runs once after pressing
// reset or powering up the board.

void setup()
  // Initialize the serial UART at 9600 bits per second.

  // Initialize the hardware digital pin 13 as an output.  The 'OUTPUT' symbol
  // is pre-defined by the Arduino system.
  // Initialize the switch pin for input.
