Ардуино как сделать многопоточность

Пример скетча многопоточности в Arduino с использованием RGB светодиода (как их подключить см. здесь) и библиотеки Thread.h

#include <Thread.h>

const int pin_led_red = A0;  
const int pin_led_green = A1; 

Thread led_red_stream = Thread();
Thread led_green_stream = Thread();


void setup() {
    pinMode(pin_led_red, OUTPUT); 
    pinMode(pin_led_green, OUTPUT); 

    led_red_stream.onRun(led_red);  
    led_red_stream.setInterval(500); 
      
    led_green_stream.onRun(led_green);  
    led_green_stream.setInterval(500);   
}

void loop() {

   if (led_red_stream.shouldRun())
        led_red_stream.run(); 
    
 if (led_green_stream.shouldRun())
        led_green_stream.run(); 
}

void led_red() { 
    static bool led_state = false;
    led_state = !led_state;          
    digitalWrite(pin_led_red, led_state); 
  }

 void led_green() { 
    static bool led_state = true;
    led_state = !led_state;          
    digitalWrite(pin_led_green, led_state); 
  }

/*
void led(int led_state, const int port) { 
    if(led_state==LOW)
  {         
    digitalWrite(port, LOW); 
  led_state=HIGH;
  }
  else
  {
  digitalWrite(port, HIGH);
  led_state=LOW;  
  }
  }
 */
