How to provide 5v supply to node mcu board? Nice detailed tut but still missing basics for newbies like how to supply 5v for the node mcu to install this in the switch board? How to give multi user access to this setup?
Thanks for the tutorial. But you forgot to tell how to add board to arduino ide. Mine have a error while Uploading the sketch. Btw with this project the light works only with blynk and not with the switch how to make it work with switch board button and blynk too?
I am facing issues with relay. My relay is getting NC to NO.. on applying both 3Volt and ground When I touch input pin of relay to 3volt of nodemcu it gets switched... And if i also connect it with ground pin of nodemcu..it also switched on
Hello my friend i made that project but only i can control my nodemcu in home. I wanna control other family persons. But its not working on other phones.how it works with multi user. I need to use it 3 person.
Can we store the data on thingspeak such as how many times a particular Bulb is turned on or off in a day and what's the usage of particular bulb? I mean ON duration, For the same project
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.
hello there, mat i ask you a question sit? i try to use IoT pproject using nodemcu for my last project. But i have an issue that the nodemcu response is too slow after i give command from blynk app. Is strength of the internet connection influencing the nodemcu response? thankyou
can we use analog as an input and output, and at the same time we use a digital input and output? or do we have to convert the analog signal into digital? Pls help me with this
Hello sir when I'm uploading it showing error esptool.fatalerror.failed to connect to esp8266:timed out waiting for packet header Pls solve my problem 🙏🏻 It port COM 7 It showing The selected serial port does not exit or your board is not connected But while uploading it blink blue led light in esp8266
hello after changing the token and my wifi network, I can't find the nodemcu board in the tools, but it must already be connected to the pc? or am I missing something?
@@TechStudyCell What voltage are you supplying to the board ? Is it 5V ? I can't power my 5V relay module even though I connect the relay with 5V input, how can you do that ?
u Need to upload the Library and if the Port is not Showing Means U need to install the Driver..... there r two of Library is there one is CP2102 and CH340
Awesome explanation. I bought NodeMCU With 4-Channel Relay Board. In that 1 relay is soldered to D3 pin of ESP. Could you explain how to use D3 pin as output? All other 3 relay is working as expected

Hi, how do you power your ESP8266 board? What power supply do you use?
Mobile charger
@@TechStudyCell What voltage are you supplying to the board ? Is it 5V ? I can't power my 5V relay module even though I connect the relay with 5V input, how can you do that ?
You can also use step down transformer, Bridge rectifier, Capacitor, 7805 regulator to get +5v dc supply to nodemcu
How can I create the timer switch..... Please tell me bro...
Modem u works with 3.3v only. 5v will damage the board
There is a inbuilt voltage regulator, so you can give 5v at Vin.
It was showing led on relayboard but no sound in the relay??
same problem with me
I m also watching this thing because to triggering relay you have to give 5volt dc to relay
@@ameenurrehman5600 did you fixed that
