Room Management System - Coding the processing - part 2

Did you try it? Did the LED come on after pressing your button number 1 and did the LED go off after just over 1 minute?

Did the LED stay on while you kept activating button 1?

Did you also try to press button number 2 and the LED went off no matter what you did with button 1?

And finally did the LED come back on after you pressed button 2 again?

If you tested all the above and you can answer all of this with yes, we are ready to type the code for the next rooms having a priority button.

We go back down to the end of our main loop and start where we finished in the last chapter:

else if(switchState[1] == 0 && lightStatus[0] == 0) { //if priority was activated and the

//lights are off

Serial.println("Priority switch deactivated switching on the lights"); //Debug only

lightOutput[0] =1; //switching on the lights

lightStatus[0] = 1; //setting the light status

roomTimer[0] = millis(); //setting the room timer

priorityStatus[0] = 0; //setting the priority for bed 1 back

//to 0

}

//set bed 2

The to days addition let us control the lights in the 3 bedrooms and the living area. The code is the same as the one we put in in the last chapter. The only thing changing is in which place in our arrays holding the variables we are pointing.

I know, looking at the numbers might be a little confusing in the beginning because we start counting the rooms and switches with 1. The first place in an array is 0. The light status for room 1 (bed1) is held in the array lightStatus[0] and the light status for room 2 (bed2) is held in the array lightStatus[1] and so on.

A little more attention we have to pay to our switches since we have two switches in some rooms.

The array switchState[0] is assigned to S1 representing the PIR's from room 1 lightStatus[0].

The array switchState[1] is assigned to S2 representing the priority switch from room 1 lightStatus[0], priorityStatus[0].

The array switchState[2] is assigned to S3 representing the PIR's from room 2 lightStatus[1].

The array switchState[3] is assigned to S4 representing the priority switch from room 2 lightStatus[1], priorityStatus[1].

And so on......

In the next chapter we will take care of the room without a priority switch.
