Is it possible to turn off / on the voltage (5V) GPIO from the command line ? ....
So turn off eg 16x2 LCD power ....Is it possible only physically eg disconnecting the cable ( 2 , 4 - GPIO)

 

 

When using the switch circuit, it's possible.
The switch circuit is possible by the photo switch or a transistor.

 

When the switch does a blue line, a backlight of LCD turns on /OFF.
