LightTaskScheduler

A lightweight cooperative task scheduler for Arduino. Schedule multiple functions to run periodically without blocking your loop(). Simple, safe, and flexible.

Features

• Run multiple periodic tasks
• Supports millis() or micros() timing
• Pause / Resume tasks at runtime
• Task priorities — higher-priority tasks run first
• Clean and minimal memory usage (no dynamic allocation)

🚀 Getting Started

Basic Blink Example

#include <LightTaskScheduler.h>

TaskScheduler scheduler;

void blink1()
{
  digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
  Serial.println("blink1");
}

void blink2()
{
  Serial.println("blink2");
}

void blink3()
{
  Serial.println("blink3");
}

Task blinkTask1(blink1, 15000, false, 3); // run every 1000 ms

Task blinkTask2(blink2, 5000, false, 0); // run every 5000 ms

Task blinkTask3(blink3, 2000, false, 1); // run every 2000 ms

void setup()
{
  Serial.begin(9600);
  pinMode(LED_BUILTIN, OUTPUT);
  scheduler.addTask(&blinkTask1);
  scheduler.addTask(&blinkTask2);
  scheduler.addTask(&blinkTask3);

  blinkTask3.run(millis()); // a way to run once at start 
}

void loop()
{
  scheduler.run();
}
