Hello!
I need to control a on-off state of a device via a GPIO output of a raspberry Pi and both units are powered from the same power supply.
For this purspose i want to use an optocoupler to act as a ''switch button'' but the 2 units are going to share the same ground.
Is this going to cause problems of any sort?
greetings
