Et ur awsome....pls make a video on ir remote controlled fan speed regulator without relay..
Pls share this project as soon as possible...
I love your videos, you are so creative. thanks for sharing.
I wish Indians would get into this field around where I live instead of scamming people with fraudulent tech support and then charging people to get their data back.
Awesome sir

Hey friend; it's a awesome project but we hate to use IC's. We love to Apply Microcontroller because it's a efficient than IC's................
you are right
very useful circuit. all components and circuit diagram should list separably.
you told we can control from anywhere but someone should be there near to answer calls manually right?
You need to put your phone on auto ans mode
👌
Nice bro
But I want to run all devices at a time....how?
can be done without using a cellphone on the receiver side?

So, you must accepting a call first to activation the led?
You can set the receiving phone to auto answer that way no-one has to be there to answer it.
Super
Nice sir
Wow!!
Dear very important question do we need balance we can run it with 0 balance? Plz replay

ok
@@EtDiscover Thank you sir....
You have to need some rectification on this project. Who receive the phone for wireless DTMF connection??? The will automatically receive after incoming call then you can the circuit wirelessly. How can we do that??

Can you make specific one means one number will turn on first relay and if we again type one number first relay gets off
look at the sequence data bas to clarify your doubts. so by that you can understand it better
Make a variable for DC voltage. 0 volts to highest volts 12or 25 48 ............1000 ????
Sir ,i am unable to get this PCB sir ,plz help me
