@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.

@@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.
Good morning sir , recently I purse two rs485 sensor one leafwetness sensor and second 7 in one npk sensor , both sensor I want two connect two single arduino , I am Trying it but result not accurate for 7 in one npk sensor , leafwetness sensor show right result please help me to correct problem
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.
I want to a make a home automation for my home. So that I am decide to control all the bulbs and fans through the home assistant or phone. I am not connect all relays and senaor through the wifi network because my home is big. Wifi range is to small for my home automation. So that I am decide to implement modbus for connect all relays and sensor. I thing Modbus is more reliable and easy to implement because the wired connection. I want to connect 10 node. Each nodes contains or hold the few relays and some sensor such as temp and humidity CT sensors mmwave sensor motion sensor. And each nodes connect through each other. And last node is finally connected to thin client or Ressbery pi which is operated home assistant os. Please solve my problem and give the feedback
Sir, ESP32 aur blynk ko use karte hue hum jo iot product banate hain usme kon sa protocol use ho raha hota hai ? Kyonki code me kahin bhi http ya mqtt to likha nahi hota.
@@JPLearning ji sir maine dekha abhi, kafi had tak clear ho gaya. Ab isme teen part hain ESP32 Blynk Desktop or mobile Isme client kon hai server kon hai aur desktop ya mobile ko hum kya bolenge ?

lekin sir slave id or holding register kaha mention kiya hai code mai or agar data modscab software mai dekhna ho toh ( mera mtlb ki abhi aapka data serial monitor pe show ho raha hai lekin agar data muje modscan mai dekhna hai jo aapne sender banaya hai ttl- rs485 se ) mene koshish ki thi lekin sir mera code error de raha hai 226 ka. please ek sjhma dijiye
@@JPLearning thank you for reply sir. lekin sir code error 226 kyu de raha hai jab mai value integer mai send kr raha hu or slave (node id) bhi bana rakhi hai mene 1 or holding register bhi banaya hai phir bhi error aa raha hai
I am making a project to detect beep sound and send a notification to my phone... But I wanted to ask that's Whether chatgpt is capable of writing the codes.. If not then how can I write it
Hello sir, can we read and write value if we use pid controller( selec pid500) for heater. it have rs485 communication, if yes how to read and write plz guide sir.
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.
