5 Pin Relay
hi all, i´m trying make switch current voltage relay.
for first, doing switch on led (better start basics) bought 2 relays, 1 5v , other 12v test them.
all references saw on internet, forums, fritzing , everywhere, relays different mine, in pin numbers , position, dont figure how wire it; these have 5 pins
i following simple tutorial (in spanish, sorry, diagrams clear understand, easyest found, in fritzing image think missing 5v wire breadboard) :

any relay expert can me? think burned 5v 1 already, want test other 1 properly
thank you¡

that website nonsense...
you must use transistor (or mosfet) switch relay, , __must__ have free=wheel diode
to prevent inductive kickback destroying transistor , arduino.
the arduino playground explains how this.
the diagram post shows how relay wired internally, can check a
multimeter.
