I'm trying to setup an automated garden as a quarantine project for my mother and I can't really figure out how to properly wire a 12V 5-pin relay module as every tutorial online only shows the ones that come in a board (those are extremely expensive in my country). I have all the components needed: resistors of all types, the relays itself, a raspberry pi, a power source for everything, the lights I'm controlling and wiring; But I just can't find a way to put everything together and control the lights in my project! My objective is to be able to control the lights through the GPIO pins on the Pi.
This is the type of relay I'm using (ignore the voltage on the image, the seller has a bunch of models):
