A lightweight cooperative task scheduler for Arduino. Schedule multiple functions to run periodically without blocking your loop(). Simple, safe, and flexible.
- Run multiple periodic tasks
- Supports
millis()ormicros()timing - Pause / Resume tasks at runtime
- Task priorities — higher-priority tasks run first
- Clean and minimal memory usage (no dynamic allocation)
