Is it possible to control a small motor, such as a motor that works with just a few volts, very far from you, using cell phone ? I am beginner. Can you guide me in the right direction?

 

Yes, you call up someone who is near the motor and instruct them to turn it on.

In all seriousness, though, you would use an IOT (internet of things) device to do than from anywhere you had an internet. I don’t know if there are generic remote controls that can do that, but there should be.

 

Welcome to AAC.

It would help us to help you if you would explain what the purpose of the motor and controller is. With the current information, the answer is going to be “yes, maybe”.

What problem is the motor/remote supposed to solve?

Also, how much are you willing to learn in order to do this?

 

the motor will open and close one of my window curtain when i am not home. i already have idea about how to do moving mechanism... but how do i make the motor work remotely... i connect motor to my home wifi or to internet directly? how? and then how my cellphone connects with that?

Use a light sensor to close the curtains at dusk and open them at dawn.

A platform like Blynk is a good way to do what you want without having to write your own mobile app. It is very mature and they offer a free tier which is almost certainly enough to complete this project. For about five dollars a month you can get a lot more, but it isn’t mecessary.

Thanks @Ya’akov for mentioning Blynk. I’ve been looking for something like that for a while.

 

Mysensors can be used for all kinds of sensing and control. Here's an example of controlling roller shutters:

Or use Sonoff smart switches:

Those can sometimes be flashed with Tasmota firmware which has various benefits like not needing to use Sonoff's app or their servers. Or you can go with cheaper generic ESP32 relay modules and Tasmota. But maybe for remote access it'll be easier to go through Sonoff's server.
