In this tutorial, I will show you how to control a relay module with NodeMCU ESP8266 using blynk app. After watching this video you will be able to do IOT Home automation using Nodemcu Esp8266 and Blynk App.

Sir can you please explain how to use this with new blynk app
What type of power source did u used? Is it ok to used mobile charger to suppply the espnode mcu? How many amps needed?
a 5v relay draws 90mA current. here the total current for two relay 180mA. and a nodemcu esp8266 chip can draw maximum 170mA current. so, 500mA or above power is OK for this project.
so, you can use mobile charger with current 500mA or above
Thank u 😊
@@jeremytiempo9639 thank you too
So mobile charger 5v 2A is ok
@@tusharpakhidde7624 yes
Will that work when you on holiday 1000 miles away or you have to be in range of your WiFi?
1000miles away
Does using relay always cause a problem?
sir how did you made the power supply?
Bro I'm trying the same with my Lolin, but it's not connecting. I've heard about how unstable Lolins are; is there any way to make it work?
My microcontroller is not taking instructions from my phone through blynk application, all it does is switch on that pin and that's it.
flash your nodemcu. and upload the code again. also, let me know the results
@@AhmadLogs Hey Ahmad, thanks for reply. After checking with multimeter, I'm getting an output of 1.7V and 5V on the D0 pin when switched off and on using Blynk. So I guess the nodemcu is working fine, but the issue with relay is that it gets triggered with 1.7V instead of it being 5V DC. Are you facing a similar issue? I just bought a new relay module today, and it's also getting triggered at 1.7V. Can you please help me out? I'm new to electronics. Is it the problem with relay again?
@@abhiraj.sharma my relay module triggered at 2v.
as I know,
The relay is triggered when the input goes below about 2 V. That means if you send a LOW signal from the Arduino, the relay turns on, and if you send a HIGH signal, the relay turns off; it works with inverted logic.
Very good! Please send me the SKETCH.
It will be better if IT can be controled manually also
Super sir
a bundle of thanks
Please add ir remote and manual switch control
How can I draw the diagram pls
Aoa!
I hope u r fine.
How add include eeprome feature
my latest videos have this feature
Sir if I want control 8 channels relay please explain how is it to make possible?🔍
make all the 8 relay pins as output. then you can make these pins LOW or High to turn ON or OFF the relays
Both bulb red wire is phase?
red wire is 5v DC
I am asking bulbs red wire
@@novagaming5789 ok.
green bulb red wire is phase
yellow bulb black wire is phase.
where is the code for gps tracker i can't find.can you provide me some source
please check the description of the video
which wifi name and password we need to enter here , please explain
your internet routers wifi name and password.
How to two phones are with one nodmcu
please explain a bit
@@AhmadLogsHow to two phones are connect with one nodmcu on blynk app
@@dainyalazam23 unfortunately, I have no idea about it
@@AhmadLogs but its possible
@@dainyalazam23 can you please give me some more details?
