Hi everybody,

I would like to know if it is possible to replace the control of the relay in the example sketch "Relay actuator" by the lauch of a sub function.

Currently, I have an Arduino node (relay actuator) with 2 optocouplers that simulate buttons for a second Arduino board that control a homemade system for my rolling shutter.
The idea is to have only one Arduino board.

I am a newbie in sketches modifications and I would like to have your opinion before to have problems, so, thank you for your help.
