Hello arduino fans!
I am working on a project but did not find any solution yet how to resolve this with an arduino or ESP.
The main idea is this: When I presings a button through arduino, it runs a command on a pc, for example a command prompt wget script or something else.
Is this possible with arduino?
Can somebody help me with a little guidance?
Thank you so much!! 
Does the PC have Bluetooth? Can you write code on the PC that will read bluetooth and execute the commands sent from Arduino? Bluetooth modules are easy to interface to the Arduino.
Wifi is another option.
Either way you must have code on the PC, written in your favorite language, that can receive and execute the commands. That part is outside the scope of the Arduino forum.
Also whichever method you use would depend a critical factors;
How far apart are the Arduino and the PC, and where exactly are they ?
Often a good idea to describe the actual project, rather than just provide redacted details.
Thank you for your help, sorry, I was not accurate too much.
The arduino is in a 1-2 meter circle close to the PC. I could use or bluetooth or wifi communication.
The project idea is: I press a button hooked to the arduino, after that it starts a motor, it spins 30 sec and on the end send a command to a computer to execute a command prompt wget to copy some files from a http server to the computer.
I dont know how to send the command wirelessly to the pc?
Thank you!
