Useing mobile instead of Arduino

Only I want to know Why should I use Arduino to run a robot?
Why can’t I use a mobile phone directly to send data to run a motor - for example -?
Sorry for any error I am using a translator!

Did you think at all before asking that?

Like sending command to, let's say, wireless (not wifi, not uC at all) hand drill for example, from your cell phone?
How is your mind working today?

Cheers,
Kari

You don't have to use an Arduino if you don't want to. This Forum is for people who want to use Arduinos.

There has to be something (but not necessarily an Arduino) to receive the data from the phone and make the motor operate.

And an Arduino cannot make a motor operate. All it can do is send signals to a motor-driver module. It is the motor-driver module which controls the flow of electricity from the power supply (maybe a battery) to the electric motor.

Sorry, I didn't understand what you meant.
You should ask about using Arduino, but consider not applying Arduino.....
I have been using it all the time and you need to have a deep understanding of it.
Thank you.

To whom were you referring when you used the word "you"?
