Arduino: Self Restart Through Code

Recently I got an Arduino project to prove my worth as a micro-controller laboratory assistant.

However, at the time, when I was trying to use the sensor, suddenly my Arduino became
unresponsive because the sensor was producing a negative output.

Then, the urgency of self-restart made me search for a solution. Luckily, someone had already done it using wdt.h library.

To use the function, you need include wdt.h library like this.

#include <avr/wdt.h>

We will use two functions: wdt_disable and wdt_enable, as you can see below

void
myreset(void) {
  Serial.println("Aku nak restart");
  wdt_disable();
  wdt_enable(WDTO_15MS);
  while(1) {}
}
