blinktimer does not name a type

My esp offline, whats wrong?

Sum time server problem den sistem is not working what will do

Superb 👍

Can i use esp32 cam model instead of esp32 dev kit ?

Bro can i have your circuit picture on real life because the switch is not useful . U can email me if u dont mind

Thanks very much, this is the best !

Gives an error message signal killed.

what about resistor you have connected

i have to turn on my mobile hots pot wifi? to control from mobile

I want to use 8 channel relay module please guide me

why when i power on esp32 my all relay on, after connect to blynk its off and work correct

We are doing same project in our college and we gave outside for module but he is cheating us by telling 20000 cost for this module? Is this true?

Including PCB board print

How much it will cost for full module sir?

hello.
I get an error with char ssid.
Do you enter your smartphone's Bluetooth ID / password for char ssid and char pass?

Gracias por enseñar como se realiza el proyecto en Blink!! Había probado algo similar con Arduino IOT pero mi Esp32 se traba, no se conecta o se cuelga

Sir. 8 channel relay home automation on video. Plz

もメンタルSwitchはregisterを入れるのですか？
いれるのなら抵抗値を教えてください。

Relay isn't working with blynk

Not conecting esp to blynk

i am ameen from pakistan i have seen your NODE MCU ESP32 video. In which you have controlled the electric power. I have a problem. I would like to have a 3 stepper motor. clock and anti clock ways. Can you please tell me the circuit?

Brother... it's giving error

BlynkSimpleEsp32.h :no such file or directory
How to resolve it

Sir do your ESP32 auto connect to wifi when for example there is power interruption?

Sir my esp32 blue led is blinking but not create wifi plz help??

Thank you friend for sharing, congrats! You have gained a new subscriber to your channel

Very nice video. If you have the time, I’d like to see a video showing how to enter WiFi credentials via the mobile app, instead of embedding them in the ESP32 firmware. If I understand it correctly, the new Blynk 2.0 allows you to do this. Thank you!
