I'm trying to build a simple mechanism but I have 0 electronics skills so here I go:
I'm trying to use GPIO17 to trigger a remote control button.
I connected it as in the following schema(s/led/remote control):
The optocoupler is a 4N25. and I have power on the right side, so I only need it to act as an on/off switch.
Seems to work but I should probably add some resistors in there... can anyone advise?
