Switch_lib library helps you to handle simple operations on digital pin states:

• Use simple and intuitive functions to switch digital pin states
• Turn HIGH/LOW digital pins with attached temporizators, timecounters and periods of time
• Use this counters and timers to control relays and devices with ease
• Switch_lib does all this timeflow control without using Delay function or RTC clocks, just plain and simple Arduino code

• Requires a pin on where to actuate and the definition of the initial state of the pin ( HIGH or LOW )

Switcher light(int pin, bool initial_state);   //initial_state = HIGH or LOW
void setup()
{
  pinMode(pin,OUTPUT);            // pinMode should be defined during setup
  digitalWrite(pin,initial_state);// digitalWrite should also be defined during the setup
}

• Switch state of the pin based on the initial state, we can call Start() and Stop()

    light.Start();            Switch ON the light
    light.Stop();             Switch to the init_state

• Turn to the initial state after any desired time: seconds, minutes or hours.

void loop()
{
  if (condition == TRUE) {
  light.Start();                   //Timer requires initialization, see example section.
  condition = FALSE;
  }

  light.Timer(5,0);  //It will keep lights ON for 5 seconds
}

light.Timer(long on, int unit);

• on: Desired time

• unit: Defines the time unit to use

  • 0 for seconds,
  • 1 for minutes,
  • 2 for hour

  Timer requires initialization using the Start(); See examples section.

• Switch the state of the pin every certain time: Like 1minute ON, 5 minutes OFF

void loop()
{
light.Period(14, 8, 2);  //14 hours ON, 8 hours OFF
}

Period(long on, long off, int unit);

• on: Desired ON time

• off: Desired OFF time

• unit: Defines the time unit to use

  • 0 for seconds,
  • 1 for minutes,
  • 2 for hours

  Example: Period(14, 8, 2); 14h ON / 8h OFF.
