** (Important) Please don't connect both NodeMCUs with the laptop at the same time. And also use different 5V power supply for each NodeMCU. Otherwise,  false turn on and off may take place. Thank you.

I LOVE your videos man, great work. I was wondering if you ever thought about creating a small guide for people just starting out.  For example one of the things I'm finding challenging is how to know when to use resistors or capacitors in a project, and how to calculate its values. Thanks once again!

MANUAL SWITCHES IS NOT WORKING PROPERLY, RELAYS ARE SWITCHING ON  & OFF CONTINUOUSLY FOR SWITCH 2, 3 & 4, SWITCH 1 COULD NOT OPERATE RELAY 1. ALSO RELAYS ARE GETTING STUCK SOMETIMES AFTER SWITCHING OFF. WIFI LED IS ALSO NOT GLOWING THOUGH CONNECTED TO WIFI AND OPERATIVE THROUGH BLYNK APPLICATION (BOTH WEB AND ANDROID APPLICATION). PLEASE HELP TO RESOLVE THE ISSUE. I AM USING Node MCU ESP8266 V3 (LOLIN CH340 chip).

@bbdas52

@arkamondal13

I made a same to same project.but pins are different.d1,d2, d5,d6 . I use seperate power supply for node mcu and 4 relay's. After starting the project, only relay 2 connected with d2 toggles. Rest are controlled by blynk or manual switch normally. If i change the output d2 pin to another relay, same problem occurs. I dont understand what's the problem is! Please help.
Thanks in advance.

@iyyappaniyyappan2565

Bro many km we can control the bulb 💡💡

@asadmirajofficial6206

How to connect 2 or 3 mobiles with a single nodeMcu. Because in 2 or more mobiles blynk apps have 2 or more AUTH token numbers.
So how can we adjust many AUTH tokens in a single Code

@pierricdoublet6248

Super,thanks for sharing. Do you have the same possibility on blynk 2.0?

@muhammadnor4135

help me sir, why is pushbutton number 1 not working even though it has been installed according to the scheme, the relay can only be turned on / off using the blynk application, what is the solution?  thank you

@matthiash.454

You have 220 volts AC___bulbs connected to the output of the relay I want to connect WS2812B__ 5 volts DC is this possible ?
