Room Management System – Coding the processing - part 4


To code in the checks for the AC-units we go again all the way down to the end of our main loop:

else if(switchState[13] == 0 && lightStatus[9] == 1) {                               //if no PIR was activated and
                                                                                                                 //the lights are on
Serial.println("We are checking the timer");                                                 //Debug only
currentTime = millis();                                                                                //setting time reference
endTime = currentTime - roomTimer[9];                                                    //calculating the inactive time
if(endTime >= delayTime[9]) {                                                                  //comparing inactive time with
                                                                                                                //delay time
Serial.println("We are switching off the lights");                                          //debug only
lightOutput[9] = 0;                                                                                   //switching off the lights
lightStatus[9] = 0;                                                                                    //resetting the light status
roomTimer[9] = 0;                                                                                  //resetting the room timer
}
}

To control the AC's we use the same code as for controlling the standard light output without priority. In praxis we only connect a read switch to the input and not a PIR. If you like to try the new implemented code, it will not work until the next chapter when we code the master relay since we are checking if the master relay is switched on. The array “lightStatus[14]” will be holding the status of the master relay which is still set to 0.
