SimpleLed is an Arduino library that controls the on, off, and blink functions of LEDs. It's a particularly simple project that aims to control LED blinking without using blocking delays.

You need to include SimpleLed.h in your project.

#include "SimpleLed.h"

After initializing the LED pin, the LED will be set to the off state by default.

To turn on the LED when the pin output is high:

#define LED_PIN LED_BUILTIN

SimpleLed led(LED_PIN);

Or:

#define LED_PIN LED_BUILTIN

SimpleLed led(LED_PIN, HIGH);

To turn on the LED when the pin output is low:

#define LED_PIN LED_BUILTIN

SimpleLed led(LED_PIN, LOW);

    led.setState(SimpleLed::LedState::ON);

Or:

    led.setState(1);

Or:

    led.on();

    led.setState(SimpleLed::LedState::OFF);

Or:

    led.setState(0);

Or:

    led.off();

The LED switches state every 1s (on-1s->off-1s->on ->...) and you need to call update() in loop():

void setup() {
    led.setState(SimpleLed::LedState::BLINK, 1000);
}

void loop() {
    led.update();
}

Or:

void setup() {
    led.blink(1000);
}

void loop() {
    led.update();
}
