Sir can you help me in my final year project my project is "IOT BASED stepper motor position control"in this we are using node mcu

[@protechnology550]

Sir hum dunya k Kisi bhi Kona se relay control krsaktay han Just like hum agar office m han or Pani ki motor on krni ha to office se on hojaye gi?

[@TechStudyCell]

Yes. If the NodeMCU connected with the Office WiFi. Your mobile and NodeMCU are connected to Blynk server. So when press the button in Blynk app, it send the signal to Blynk server through the internet. And the NodeMCU received that signal from Blynk server.
