https://forum.etechnophiles.com/arduino/watchdog-timer-in-microcontrollers/ Hi, Welcome to the eTechnophiles forum. Got a question like, \'What resistor value to choose for your simple LED project\' OR \'Where is the resistor connected to the inbuilt LED in Arduino UNO\'s schematic\' - All will be answered here. Feel free to check out the topics below. en-US Fri, 22 May 2026 22:00:06 +0000 wpForo 60 https://forum.etechnophiles.com/arduino/watchdog-timer-in-microcontrollers/#post-413 Fri, 28 Mar 2025 05:04:25 +0000 A watchdog timer (WDT) is a hardware timer that resets the microcontroller if it crashes or freezes. The system must periodically reset the WDT ("kick" it) to prevent a reset. If it fails, the watchdog assumes a fault and restarts the system

After looking into it, I’m even more confused. I get that it’s supposed to reset the system if something goes wrong, but how exactly does it work, and when is it needed? Hoping to get some clarity on this.
