Relay phone sa operation nhi ho rha ha

[@RakeshRaiger-ei5ot]

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

[@anshukumarsingh95]

It's a very good project.....thanks for detailed video

[@SOURAV10MAY]

Awesome 👍

[@abhishekkumar-hp2rl]

Great work

Thanks
100 % working

Code copy nahi ho raha

[@sanu7210]

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

[@SajjadAli-gb4dl]

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

[@giteshchafekar572]

can we use same code with other own created app

[@donaldiro5398]

Can this work with HC 04 Bluetooth module

[@Kai-dg4go]

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.

[@sanu7210]

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

[@prakashghose7518]

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

[@MakeloGy]

uno is connected to circuit of relay board ( for circuit functions ) and on relay board u can also connect additional supply for relay

[@yuvasivasaikumar]

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

[@MakeloGy]

No problem bro it's just how this project work

[@technicaljd4823]

Same

[@technicaljd4823]

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

[@bo_bo_da]

Bhai relay module ko 24 ghante 5 volt ka current do to William model automatic on nahin hoga what 24 ghante 5 voltage rahana chahie relay module mei😮n usk😮e liye battery ka istemal kar sakte hain with charging😮

Sir ye kitne price me ban jaiga overall?
