+Arduino Cloud sketches use a **Watchdog Timer (WDT)** by default, however, not all boards support this function. The WDT can be used to automatically recover from hardware faults or unrecoverable software errors.
 
 A WDT is essentially a countdown timer, whereas it starts counting from a set value, and upon reaching zero, it resets the board. To prevent it from reaching zero, we continuously call it from the `loop()`, using the `ArduinoCloud.update()` function.
