Hi, I can't find a simple library for doing that, avr/wdt.h doesn'0t work properly, I can't figure out how to searching everywhere, I don't need sleep mode, I just need to reboot in case the CPU hangs for any reason.
Thank you a lot!

This doesn't work, it does one reboot, then stucks.

#include <avr/io.h>
#include <avr/interrupt.h>
#include <avr/wdt.h>

void setup() {
    wdt_enable(WDTO_2S);
}
void loop() {
     //   wdt_reset();
    }

clearing every setup the watchdog flag MCUSR &= ~_BV(WDRF); doesn't help too

I've solved by updating the Bootloader of Digispark, I strongly recomend everyone to do so, it's easy and via USB. Earlier versions have many bugs!
