Wiring a bare relay without a module to Arduino

Customer:

I need detailed guidance on how to wire a relay directly without a module. The relay I purchased has 5 terminals. I need to connect VCC, GND, and a signal line from Arduino/Croduino to it, and connect a load to the normal open and COM terminals. How should I connect all of this?

Kao nastavak na današnji telefonski razgovor, zamolio bih detaljno pojašnjenje načina spajanja releja bez modula, drugim riječima, relej koji sam kod Vas kupio bez modula, ima na sebi 5 izlaza, a ja moram na njega spojiti vcc, gnd, signal sa croduina, te na izlazima spojiti trošilo na normal open i COM,

Pitanje glasi, kako da sve to spojim bez modula?

Hvala​:blush:

Here are some useful links that explain how to use a relay by itself, without a module, with Arduino/Croduino:

šaljem par korisnih linkova koji objašnjavaju kako koristiti samo relej, bez modula, s Arduinom/Croduinom:
