Nice sir ji
Mene ye project banaya hai bahut achhe se kam kar rha hai 🎉🎉🎉🎉🎉🎉🎉

[anshukumarsingh]

It's a very good for detailed video

[obeidanas]

Instead of normal relay have you used modbus relays over rs485 for long range activation of relays.

Sir muhy 1 chai hai ue kitny ka mily ga 8 channel

[UniqueBoySiva]

Hiii Bro ...
My name siva ....
Home automation But switch on the circuit Board ... All relays are on condetion. That is the problem.... Plz respond

[kishorkherkatary]

Sir is the Bulb connected to the adapter ?

[kuntalbhatt]

Can you tell me from where i can buy these components . I mean online website

[sanu]

bhai function revers karna hey, matlan yeh code main jab apps on kar raha hu tab device off ho raha hey, apps sey off karney sey blub fan on ho raha hey SO CAN I REVERS THE LOGIC A = HIGH, a=LOW

[technicaljd]

Bro first time all relays on ho jata nai...next time sahi kaam Karter first time toh off hone solution?

[prakashghose]

If you are giving power to Rellay from another source, then why did you connect GND and Voltage to relay from UNO?? Kindly tell.

[donaldiro]

Can this work with HC 04 Bluetooth module

[sanu]

P brother main problem is apps is not installed and not working on my phone so what is the solution in that case

[dyt]

Sir ye kitne price me ban jaiga overall?

[Kai-dggo]

Hello.
This is a good idea video, but I can't install it because the Android app is not compatible with Android 14.
Can it support Android 14?
I would like to add 5 seconds, 10 seconds, 20 seconds, and 30 seconds to the timer if possible.
thank you.

[giteshchafekar]

can we use same code with other own created app

[samratautomationworld]

sir code uploade karne par error aa raha hai

[kiyna_kibateiy]

But who will code get into the device?? Usse code ko kis pe dalla😅

[aashishchauhan]

Sir mere ko code chahiye 2 channel relay ka

[quangmi]

bạn không cho đoạn mã thì bạn cũng chỉ là người copy mà thôi! Chẳng có gì đặc biệt với tôi.
