I would like to reset my Arduino UNO


In most cases you can do it just by closing and reopening the serial port. But why do you want to reset it?

I just would like to take control my Arduino without touching it, it's cool if I can reset from distant afar.

The question is why? Opening and closing the serial port resets the Arduino, unless you've modified. That seems sufficient to me.

If being 'cool' is your only reason then I don't see any point. It's not as if you will get to see those LEDs flash briefly as it resets. And what other reason would you have for wanting to reset it?

Just be sure your arduino board is one that has a WDT friendly bootloader such as the current UNO, as older and current mega boards for example will 'brick' with short WDT interrupts, requiring you to reburn the bootloader to recover.

So how to software reboot MEGA then?
