Ok, I have this awkward situation. I have a 3V relay that I need to implement in my project. When I connect it to a 5V pin on RPi, everything's working fine, I can hear the coil opening and current flows from the relay, but when I try to do same thing with GPIO pin (without resistor), it simply doesn't work. I guess, gpio pin doesn't provide enough current to the relay to open the coil, because as far as I know, gpio pin is 3V, just as my relay.
Relay model is LMR2-3D
So what's the solution in my situation? I heard that it's possible to increase current for gpio pin, will this solve the issue I have or is there a better solution?
P.S. As you may have guessed, I'm quite new to electronics.
