          Hi @Geethesh,

          Thanks for the quick replay, the pdf is about 28BYJ-48 model it's comes with 5 pins, but I need 28BYJ-28 it comes with 4 pins.

              @salmanfaris I've not used the same version of the stepper motor that you've mentioned but I've used 12V stepper motor with ULN2003 motor driver. So probably I can help you with the queries.

              Firstly all the tutorials on the internet show how to connect your motor's wires to ULN2003. But, in reality when you buy those motors the wires color codes may be changed, so in that case, we need to use a multimeter and check the resistance of the wires. 2 wires will have the same resistance and other 2 wires have the same resistance and the leftover one is a ground wire. This way we can get to know which wire must be connected to which port of ULN2003 driver. This is the common doubt all get while using ULN2003.

                @salmanfaris Actually, I can't connect my NodeMCU device with the localhost server. I can establish a connection using the test.mosquitto.org server.
                This is my required case: YouTube link

              • @sivanath From your last message looks like the MQTT broker already running on your computer. Could you please try to do a test with nodeRED and see it's working or not.

                @swalahamani I may not be able to come tomorrow. I think we could set up a call. How can I contact you personally?

                Oh okay.

                Please bring your device if you're coming for the upcoming MakerChat 0x13 tomorrow (IST). Either I and @salmanfaris or both of us will be there.

                Or else we can set up a call sometime this weekend or the next week and sort it out.

                Let me know.
