Before we learn how to reset an Arduino using code, let’s talk about the hardware reset. It’s actually possible to use the hardware rest from code too! On the Arduino you will find a button. Pressing this button is a hardware reset. Almost all of us have done this at some point i...
Note that that the reset pin cannot be used as a GPIO when using a bootloader. It doesn't matter if you have set the reset pin as GPIO in the tools menu or not; the bootloader option will override this setting. Supported clock frequencies MegaCoreX lets you choose what clock frequency ...
// reset the debouncing timer lastDebounceTime = millis(); } if ((millis() - lastDebounceTime) > debounceDelay) { // whatever the reading is at, it's been there for longer than the debounce // delay, so take it as the actual current state: // if the button state has changed: if...
If you're not planning to use the bootloader (uploading code using a USB to serial adapter), the FTDI header and the 100 nF capacitor on the reset pin can be omitted. Open theTools > Boardmenu item, selectMightyCoreand select your preferred target. ...
