This example implements a rule that is: 'keep the WLED on the first ten seconds of program execution' You could define your own rules, for instance: - turn on heat if temerature drops below x - if the light is red, stop the car

#include <Supervisor.h>

int x = 0;

  Define the rule itself
SupervisedRule<int> ledOnFirstTenSeconds(x,checkFirstTen,handleAfterTen);

  Define the rule helpers
//this function will return true the first ten seconds
//when it return false (aka the rule failed) the handler will be called
boolean checkFirstTen(int x) {
  if (millis()<10000) { return true; } return false;

//the first ten seconds have passed
//turn off the LED and remove the rule
void handleAfterTen(int &x) {
  digitalWrite(WLED, LOW);

void setup()

  digitalWrite(WLED, HIGH);

void loop()
