[chetan]

Hi Friends,

 

This is my first post,

 

Is there any way to operate relay by computer (By USB Port), i have already operated relay by printer port.

 

Because of my laptop have USB port only,

 

Please give circuit diagram and useful information,

 

Thanks in advance.

hi…

 

 

 another option is that, u can use usb to serial(RS232) convertor….

and control relay serially…. it’s an easier method.
