CONTROL YOUR ELECTRONIC APPLIANCES FROM ANY PLACE IN THE WORLD

A great app what can do a loot of staff
1) Take a photo and send to your mobile phone, by using your old phone(only you need is your old phone, no need any arduino or esp32)

2) Switch the relay(tourn on/off the light or any home appliances), by internet, or SMS or Email
3) Make your own bulgary alarm / security systems, it will send and email or sms when detect moution from sensor and arduino or ESP32 will send data by bluetooth to your old phone. Check the link bellow there will be the scheme how to do this.

4) Worry you forgot the cooker ON you can use your old phone for this to request a photo and the app will take a photo and send to your phone, isn't this great? (only you need is your old phone, no need any arduino or esp32)

If you want to use this app to taking a photo and get it to your mobile phone, than you don't need any arduino or esp32 just install the app on phone what you want will stay in your house or garage

This app comunicate with arduino via bluetooth using HC05 or HC06... or ESP32, it allow you to create switches what you can use for door lock or tourn on/off the light or the heater direct from your phone and the most important you can do this from around the world, by connect to internet if you dont have a internet connection you can control it by SMS.

What you will need for doing this:
Arduino any version and Bluetooth HC05 or HC06 or ESP32
Relay Module
And the app

Arduino its a small microcontroler the price of it start from $1.5 where you can program it to do any operation like switch the relay or get data from sensor like temperature or control any DC or Stepper Motor and not only.

Also this app could be used like security alarm conect to arduino a Motion Detector Sensor and when sensor detect motion send text by bluetooth via serial to the phone and it will send you an email or SMS, isn't that great?.

But if you want to control the arduino via internet or sms you will need your old unused phone to do this.

So how it work when you tourn the switch on it will send by bluetooth data like 22:on
tourn the switch off it will send by bluetooth data like 22:off

22 - id of the switch(you can get/change it from add/edit switches)
on - message
so on arduino side will be like this


if(returnData("22", "off")){// the id of the switch from app (you can find it by press add/edit switches)
digitalWrite(relay3, HIGH); // for some rele when pin is HIGH the relay is disconnected
}else if(returnData("22", "on")){ // the id of the switch from app (you can find it by press add/edit switches)
digitalWrite(relay3, LOW); // for some rele when pin is LOW the relay is connected

relay3- its the pin of the arduino (digital pin pin what name start with d1,d2)

you worry how to write code for arduino don't have to, check the link bellow

Check the link bellow there is the code for arduino, there it's the scheme and code for Arduino and ESP32 how to create a bluetooth Smart Plug, and explanation how to do.
