Heroku ek cloud service hai

@JPLearning please bro rply read kr mujy lazmi jawab dejiaga, mera ek video calling wali application hai, dosry developer ny mujy build kia hai, msgs k liye hum ny firebase ka use kia hai, and video calling k liye hum ny agora ko use kia hai, ab swal ye hai keh developer ny ye heroku ko b use kia hai, ab mujy thora confirm karein, heroku ka kia kam mere app k undar, same mere app ki tarah ek our app hai video calling wali wo kisi our ka hai, ab s ny mujy kaha, msgs k liye mere firebase ko use kia hai and video calling k liye agora use kia hai, liken s ny heroku ko use nhi kia hai pr b heroku ki bagher us ki app chalti hai to per developer ny mere app mn heroku ko kion use kia ta , please thora ye confusion dor karein and ye btau app k undar heroku ka kam kia hai ?

@@AdSensemaster1 Dekhen heroku jesy mene btaya k ye applications deployment tool hai cloud pe or apky case me may be usny koi service banai hogi jo Agora and Firebase ko use kr k complete system bana rahi hogi or wo application Heroku pe deploy hogi to use in your web/mobile app.

It's a simple monitoring sensor you can use it for your feedback

@@JPLearning ok , i can use both of the reed switch sensor and magnet reed switch sensor?

Yes

You can find me on LinkedIn

I need to check it if it's possbile I'll do it

Now, here it is

@@JPLearning thanks .

Hello revin, Yes, you cann add buzzer on any GPIO and define it into code as Output and trigger when door's open.

@@JPLearning on any GPIO pin, but i study the active piezo buzzer , that require the 5V to more power to operate . so i can choose the pin 4 for buzzer is right choice or not. otherwise i will use the relay.

You can use pin 4 to give LOW signal from GPIO and HIGH signal you can give directly on buzzer

@@JPLearning Hello Revin, do you help me in final year project?

You can check guide into the documentation it's difficult process

@@JPLearning Dear Brother can i use one cerifacate in many esp8266?

@@MahtabKamal In this case this is server certificate which will use for every client/device you don't need to generate new one.

Hi prakash

@@JPLearning have nice day sir. 👌🙏👍

InshaAllah next video me add kr duga

@JPLearning thank you so much, Sir.

In this thumbnail I used Photoshop

No, It's already installed when you install ESP8266 board.

Thanks

Thank you for understanding.

Thanks

Mene AT commands se kbhi working nahi ki me jaldi hi kr k video record dal duga. Thank you for your suggestion.

My pleasure

Ye mene kafi videos me show Kya hai ap dekh Len or videos apko idea hojae ga

Kya matlab me samjha nahi apki baat

Dear prashant, You need to modify slave ID first of one of any sensor like leafwetness Slave ID 1 and npk sensor Slave ID will be 2 and then you can read both sensor with single rs485 module or otherwise you can use 2 different rs485 modules for each sensor so in this case you don't need to modify slave ID.

Thank you so much 😁

HTTP is request and response protocol even WebSocket is working on publish and subscribe method for real time data sharing

I don't if it's possible or not may be you can try to pass gsmClient instead of WiFi client

How we make please help me by code

It depends on your sensor how to integrate it with your controller.

Now changed and thank you

Hi Parveen, Yes, we can read and write if your pid controller support modbus protocol and for that you need read manual of modbus communication of your pid controller.
