ESP8266 WEBSERVER RELAY CONTROL and alarm on off

Projects Programming
1

These codes work normally,

I want to add alarm motion detector to these codes, how can I do it? and I want to make the alarm active or passive with 1 button

I use the device esp8266 nodemcu

What I need to add to this code, I want to compile both the relay control and the alarm system, I would be very glad if you help. I want to activate or deactivate the alarm with a button

i want this codes, merge, and add alarm on/off button

i want this codes, merge, and add alarm on/off button

Toss the code in a blender, and hit puree, then. Who knows what you'll get.

If you have some requirements for the resulting program, feel free to share them.

3

The codes have been combined, but the sensor did not work, the motion was detected in a message that did not output the serial connection on the monitor.
how do I change these codes?

I want to put a button in webserver, I want to make the alarm status open or closed,

I have a project with WebServer and relays and functions activated by relays, but it is at different level.

6 
  int state = digitalRead(PIRsensor);
  delay(500);                         //

Check for motion, and then stuff your head in the sand for a while. Why?

Why is there an empty comment? Mindless cut and paste sucks.

            else if (state == HIGH){
             digitalWrite (Balarm, HIGH);    //If intrusion detected ring the buzzer

You only do this if there is a client connected, AND the client asked for the initial page. Why is this code HERE?

I'm a bit novice, I'm doing with trial and error. Can you help?

I have reviewed, but this level exceeds me :slight_smile: How can I make changes in my codes? can you help me?

4 relay
1 motion sensor

I can control the relays, but I want to add the motion detector and set the alarm, the alarm is activated and the alarm is disabled.

8

How can I make changes in my codes?

With any text editor.

can you help me?

No, because you have not defined (adequately) your requirements.

but I want to add the motion detector and set the alarm, the alarm is activated and the alarm is disabled.

Those are not requirements. They are goals, at best. A requirement defines when to do something (like read the motion sensor or activate the alarm or disable the alarm), as well as the condition(s) under which that should happen.

Dear friend, how do I make changes to this system to control the motion sensor? I did the merge, but it didn't work, could you please review and edit the code

Dear friend, how do I make changes to this system to control the motion sensor?

You can't. Motion sensor do what they want. You can't control them. ALL you can do is react to the output when you read a motion sensor.

I did the merge, but it didn't work

You STILL haven't properly defined any requirements, do you can NOT write any code.

could you please review and edit the code

We can review the code, WHEN YOU HAVE SOME REQUIREMENTS. YOU get to edit the code to properly implement those as-yet-undefined requirements.
