Hob2Hood - Control any kitchen hood with Electrolux/AEG hob

[lonek_rwl]

I attached the schematic of my project. With original code everything works Great.

I need to change only one thing - Relays must do PULSE instead of CONSTANTLY ON/CONSTANTLY OFF

so, for example i changed the code of LIGHT control:

// control hood based on 'light' and 'ventilation' variables
void controlHood() {

  bool logLight = light!=last_light;
  bool logVent = ventilation!=last_ventilation;
  

  // control light
  switch (light) {
    // Light OFF
    case 0:
      if (logLight) Serial.println("Light: OFF");
      digitalWrite(PIN_OUT_LIGHT, ON);
      delay(1000);
      digitalWrite(PIN_OUT_LIGHT, OFF);
      delay(1000);
      break;
    // Light ON
    case 1:
      if (logLight) Serial.println("Light: ON");
      digitalWrite(PIN_OUT_LIGHT, ON);
      delay(1000);
      digitalWrite(PIN_OUT_LIGHT, OFF);
      delay(1000);
      break;
    default:
      break;
  }

But the code is gone mad. Insted of simply make ON - 1sec Delay - OFF it makes it 2-3 times. But worst part is that suddenly it makes it every time it receives other codes - when I send VENTILATION 1 signal it firstly make 2-3 times LIGHT ON/OFF and then VENTILATION 1.
