I need help.
A few months ago I started a project to control devices via a module with arduino and apc220 module, and another module connected to the server .
The idea is simple, send parameters from the server to the Arduino via RF using apc220 modules, the server is controlled by PHP and accessible from anywhere.
the problem is I can not send paramentros, PHP will not let me run the exec () function (the server uses linux via VirtualBox)
as the problem is I can not connect the module to virtualbox. I decided to use Windows but do not know how to send the paramentros from here ....
someone help me with this project?
